Mercedes-Benz GLC as a used car

Mercedes-Benz GLC as a Used Car

The Mercedes-Benz GLC has become one of the most important models in the brand’s SUV range, combining the practicality of a family crossover with the comfort, technology and premium image expected from a Mercedes-Benz. On the used-car market, it is particularly interesting because the first-generation GLC, known internally as the X253, has now matured into an accessible second-hand luxury SUV, while newer examples offer increasingly sophisticated mild-hybrid and plug-in-hybrid powertrains. For buyers who want something larger and more comfortable than a GLA or GLB without moving into the size and expense of a full-size luxury SUV, the GLC occupies a useful middle ground.

The first GLC appeared in 2015 as the successor to the GLK, and the X253 remained in production until 2022. A substantial facelift arrived for the 2019 model year, bringing revised engines, updated infotainment and driver-assistance technology, refreshed exterior styling and a more modern interior. The second-generation GLC followed in 2022, but the earlier X253 remains particularly relevant to used-car buyers because there are now many examples available at substantially lower prices than when they were new. The facelifted versions are especially interesting because Mercedes-Benz introduced a new generation of four-cylinder engines and a 48-volt electrical system on the petrol models, while the diesels adopted more sophisticated emissions treatment.

Buying a used GLC is not quite the same as buying an ordinary family SUV. It is a premium vehicle with complex electronics, sophisticated suspension, automatic transmissions and, on most versions, permanent or electronically controlled all-wheel drive. The result can be an exceptionally comfortable and capable vehicle when properly maintained, but a neglected example can become expensive surprisingly quickly. The right approach is therefore to focus on maintenance history, mechanical condition and specification rather than simply choosing the lowest-priced GLC in the classifieds.

Why buy a used Mercedes-Benz GLC?

A genuine premium SUV

The GLC’s greatest strength is the way it combines everyday practicality with long-distance comfort. It is considerably more substantial than the GLA and GLB, yet it remains easier to live with than the larger GLE. Its relatively high seating position provides the visibility that attracts many SUV buyers, while the suspension and cabin insulation give it a relaxed character on longer journeys.

The first-generation GLC is also relatively conventional beneath its styling. Unlike some newer electric and hybrid SUVs, it retains familiar petrol and diesel powertrains, conventional automatic transmissions and well-established mechanical components. That makes a used X253 relatively straightforward for specialists familiar with Mercedes-Benz’s wider model range, although this should not be confused with inexpensive maintenance.

The facelifted GLC 220 d, for example, uses a 1,950 cc four-cylinder diesel with 194 hp and 400 Nm, a nine-speed automatic transmission and all-wheel drive. ADAC lists a 1,760 kg kerb weight for this version, illustrating that the GLC is a substantial vehicle despite its mid-size dimensions.

Comfortable rather than unnecessarily sporty

The GLC is designed primarily as a comfortable premium SUV. It can be surprisingly quick in stronger engine versions, but its natural character is relaxed. The driving position is commanding, the cabin is quiet and the automatic gearbox is well suited to urban traffic as well as motorway cruising.

The available suspension systems can make a substantial difference. Some examples have conventional steel springs, while others are equipped with adaptive damping or air suspension. A well-specified GLC can therefore provide a particularly smooth ride, but the additional technology also means more components that should be inspected carefully when buying second-hand.

Which GLC generation should you choose?

First-generation X253

The X253 is the generation most relevant to buyers looking for value. Early cars from 2015 onwards can now be significantly cheaper than their original prices, while the facelifted 2019–2022 cars combine much of the appearance and technology of a newer Mercedes-Benz with more accessible used-car pricing.

Early engines included versions such as the GLC 220 d, GLC 250 d, GLC 250 petrol, GLC 300 and six-cylinder GLC 350 d. The range subsequently expanded and changed considerably. For example, 2018 specifications included a 170-hp GLC 220 d, 204-hp GLC 250 d, 245-hp GLC 300 and 258-hp GLC 350 d.

This variety is useful, but it also means that buyers should never assess a GLC solely by its model name. The exact model year and engine are important because specifications changed considerably during the vehicle’s production.

Facelifted X253

The 2019 facelift is particularly attractive as a used purchase. Mercedes-Benz introduced updated four-cylinder petrol and diesel engines, a 48-volt electrical system for the petrol versions and updated infotainment. The manufacturer described the new petrol system as incorporating a belt-driven starter-generator capable of providing boost and recuperation, while the diesels adopted more advanced exhaust after-treatment including SCR and AdBlue technology.

The facelift therefore feels noticeably more modern inside and out. The updated infotainment and driver-assistance technology can be important to buyers who intend to keep the car for several years.

Choosing the right engine

GLC 220 d

The GLC 220 d is one of the most sensible versions for high-mileage users. The facelifted model’s 2.0-litre diesel produces 194 hp and 400 Nm, with power delivered through a nine-speed automatic transmission and 4MATIC all-wheel drive. ADAC lists a combined consumption figure of 6.1 l/100 km for the specific 2019–2020 configuration it catalogues.

The combination works well with the GLC’s size. There is enough torque for effortless motorway acceleration, and the diesel’s low-speed pulling power is useful when the car is fully loaded. A diesel GLC also makes more sense for someone who regularly covers longer distances than for an owner who drives almost exclusively through a city.

The emissions system deserves attention, however. The facelifted diesel uses a diesel particulate filter and SCR-based exhaust treatment, so the condition of the emissions-control components should be established before purchase. Mercedes-Benz’s own technical information confirms the use of SCR and AdBlue technology in the updated diesel range.

GLC 300 d and GLC 400 d

The more powerful diesel versions appeal to drivers who want effortless performance without moving to a petrol V8. The facelifted GLC 300 d uses a 2.0-litre diesel producing 245 hp and 500 Nm, while the GLC 400 d uses a 3.0-litre six-cylinder diesel producing 330 hp and 700 Nm in the relevant range.

The six-cylinder GLC 400 d is a particularly different proposition from the four-cylinder versions. Its smoothness, torque and performance suit the vehicle extremely well, but purchase prices, fuel costs, taxation in some markets and maintenance expenses can all be higher.

GLC 200 and GLC 300 petrol

The petrol versions are worth considering for drivers who cover fewer kilometres or predominantly make shorter journeys. The facelifted GLC 200 uses a 2.0-litre four-cylinder petrol engine with a 48-volt mild-hybrid system, while the GLC 300 adds considerably more power. Mercedes-Benz’s technical information lists the facelift GLC 200 at 197 hp from the combustion engine plus electric assistance and the GLC 300 at 258 hp plus electric assistance, with both using 4MATIC and the nine-speed automatic transmission.

The mild-hybrid system is not designed to turn the GLC into a full electric vehicle. Instead, it assists the combustion engine during certain operating conditions and recovers energy during deceleration. This can improve smoothness as well as efficiency.

For an urban driver, a petrol GLC may be a more straightforward choice than a diesel, especially if the annual mileage is relatively low. A buyer should nevertheless compare real-world fuel costs rather than relying exclusively on official consumption figures.

Plug-in hybrid versions

The X253 facelift also introduced plug-in-hybrid versions including the GLC 300 e and GLC 300 de. These combine an internal-combustion engine with an electric motor and high-voltage battery, allowing shorter daily journeys to be completed using electric power when the battery is charged.

A plug-in hybrid can be particularly attractive when the owner has dependable access to home or workplace charging. Without regular charging, however, the additional weight and complexity of the hybrid system do not necessarily provide the same benefit.

Used PHEV buyers should therefore inspect the charging system and battery operation carefully. The test drive should include electric operation, hybrid operation and charging if practical, while the vehicle’s diagnostic history should be checked by someone familiar with Mercedes-Benz plug-in hybrids.

How does the GLC drive?

The GLC’s road manners are one of the main reasons people choose it over a more utilitarian SUV. The driving position is elevated without being excessively high, the steering is relatively easy to manage in town and the vehicle feels stable at motorway speeds.

The longer wheelbase and substantial body give the GLC a planted character, while the available adaptive suspension can significantly improve ride comfort. On larger wheels, however, some examples can feel considerably firmer than expected, particularly over potholes and sharp-edged road surfaces.

The GLC is also a good motorway vehicle. The diesel versions in particular are capable of covering long distances with little effort, while the petrol versions provide quieter and smoother operation for drivers who do not need diesel economy.

Four-wheel drive is standard on many European-market GLC versions and gives useful traction in rain, snow and on loose surfaces. It does not turn the GLC into a serious off-road vehicle, however. The vehicle’s strengths are primarily road-based, and buyers intending to drive regularly on difficult terrain should pay attention to ground clearance, tyres and the exact drivetrain specification.

Interior and practicality

A comfortable five-seat cabin

The GLC is fundamentally a five-seat SUV, and the cabin provides considerably more room than the smaller GLA. Rear-seat space is suitable for adults, while the luggage compartment is practical for family use.

A facelifted GLC 220 d is approximately 4.66 metres long, 1.89 metres wide and 1.64 metres tall, with a wheelbase of approximately 2.87 metres. The relatively long wheelbase contributes to the spacious cabin.

The interior quality depends heavily on specification and age. Well-maintained examples can still feel convincingly premium, but buyers should inspect the driver’s seat, steering wheel, switchgear and door trims for excessive wear. Interior condition is often a useful indicator of whether a supposedly low-mileage car has genuinely been treated carefully.

Technology

The facelifted GLC gained important improvements to infotainment and driver assistance. Depending on specification, buyers can encounter digital instrumentation, a larger infotainment display, smartphone integration, navigation, parking cameras, adaptive cruise control and various semi-automated assistance systems.

As always with a used premium car, equipment levels vary. It is worth comparing the original factory specification rather than assuming that a particular trim level contains every desirable feature.

What should you check before buying?

Service history and diagnostics

A comprehensive service history should be considered essential. Ask for invoices and maintenance records and check whether the mileage is consistent across the documentation.

A pre-purchase diagnostic scan is also worthwhile. Modern Mercedes-Benz vehicles store substantial amounts of information electronically, and a specialist can identify faults or warnings that may not be obvious during a normal test drive.

Automatic transmission

The 9G-TRONIC automatic transmission is fitted to many GLC versions and should shift smoothly. Test it from cold, during gentle acceleration, under harder acceleration and while manoeuvring at low speed.

Any significant hesitation, harsh engagement, repeated shuddering or unexplained noise should be investigated. A transmission problem can be expensive, so it is much better to discover a potential issue before completing the purchase.

Suspension and air suspension

The suspension deserves close attention. Listen for knocks and creaks, inspect the tyres for uneven wear and check whether the vehicle sits correctly.

Cars equipped with air suspension require particular care. Air suspension offers excellent ride comfort, but compressors, air springs, valves and associated electronics can eventually require repair. A used GLC with air suspension is not automatically a bad purchase, but its condition should be verified carefully.

4MATIC drivetrain

Most GLCs encountered on the European used market have 4MATIC. Check for drivetrain vibrations, unusual noises and evidence of poor maintenance. Inspect the underside for signs of impact or damage, particularly if the vehicle has been used on poor roads.

Tyres should also be checked carefully. Uneven or badly mismatched tyres can indicate alignment, suspension or drivetrain issues.

Diesel emissions equipment

On diesel versions, inspect the condition and history of the DPF, SCR system and AdBlue-related components. These systems are an essential part of modern diesel operation but can become expensive if neglected.

This is another reason why usage history matters. A diesel GLC that has regularly travelled long motorway journeys is a different proposition from one that has spent most of its life making very short urban trips.

Running costs

A GLC is unlikely to have the running costs of a mainstream compact SUV. Premium tyres, large brakes, sophisticated suspension and Mercedes-Benz-specific electronics can all be expensive. The exact engine makes a major difference as well.

A GLC 220 d can deliver relatively good fuel economy for its size, while the GLC 300 d and GLC 400 d offer more performance at a corresponding increase in fuel and maintenance costs. Petrol models can be economical enough for moderate mileage, but drivers covering many motorway kilometres may find the diesel more suitable.

Insurance and taxation should also be checked before buying, particularly with six-cylinder and AMG versions. A seemingly small difference in purchase price can be outweighed by higher annual running costs.

GLC SUV or GLC Coupé?

The GLC is also available in Coupé form, but the conventional SUV is the more practical choice. Its more upright rear end provides better luggage flexibility and rear-seat usability.

The Coupé sacrifices some practicality for its lower roofline and more sporting appearance. If carrying passengers and luggage is a priority, the standard GLC makes more sense. If styling is a higher priority and the reduced practicality is acceptable, the Coupé can be an alternative.

On the used market, condition and specification should take precedence over body style. A well-maintained conventional GLC is generally a more useful purchase than a neglected Coupé simply because the latter looks more distinctive.

Is the Mercedes-Benz GLC a good used car?

The Mercedes-Benz GLC is a strong used-car proposition for buyers who want a genuinely premium mid-size SUV with good long-distance manners, a comfortable interior and a broad choice of engines. The first-generation X253 has also reached an interesting stage in its life cycle: early examples are now relatively affordable, while facelifted models from 2019 onwards still feel modern enough to satisfy buyers who want contemporary technology.

The most important decision is choosing the right engine for the intended usage. The GLC 220 d is well suited to high-mileage drivers, the petrol GLC 200 and GLC 300 can make more sense for shorter or mixed journeys, and the larger diesel engines offer impressive performance for buyers who value effortless acceleration. Plug-in hybrids add another option for drivers who can charge regularly.

The GLC’s complexity means that buying purely on price is risky. A thorough inspection, diagnostic scan, verification of the service history and careful test drive are all worthwhile. Pay particular attention to the transmission, suspension, 4MATIC system, diesel emissions equipment and electronic features.

A well-maintained GLC can remain an excellent luxury family vehicle for many years. It offers more space and comfort than the smaller GLA and GLB without becoming as imposing as the GLE. For a buyer who wants a used Mercedes-Benz SUV that can handle commuting, family duties and long-distance travel with equal ease, the GLC remains one of the most versatile choices in the range.

Mercedes-Benz GLC technical specifications

The following table uses representative first-generation X253 facelift specifications, primarily from the 2019–2022 period. Mercedes-Benz changed engines and equipment during the production run, so exact figures can vary according to model year and market. The GLC 220 d figures, for example, are supported by ADAC and Czech technical data, while Mercedes-Benz’s published facelift information documents the broader engine range.

*Specifications are representative rather than universal. Engine outputs, acceleration, dimensions, consumption and equipment can differ by model year, market and optional equipment. Mercedes-Benz’s facelift documentation lists the GLC 200 at 197 hp, GLC 300 at 258 hp, GLC 200 d at 163 hp, GLC 220 d at 194 hp and GLC 300 d at 245 hp in the relevant launch specification; the later and more powerful GLC 400 d used a 2.9-litre six-cylinder diesel. *
