Mercedes-Benz GLC Used Car Buyer’s Guide: Features, Mileage, and What to Check

For anyone exploring the luxury space in the used car market, the used Mercedes GLC often lands right in the middle of what makes sense and what feels premium. Be it the petrol-powered Mercedes GLC 300, high-torque diesel, or one of the facelifted models with a sumptuous MBUX interface, the GLC SUV has always provided that daily comfort with the unmistakable Mercedes flair.

However, when buying a used high-end car that will cost you over ₹40 lakhs, details are important. Whether it is the finer performance-related details or the actual costs of ownership, this blog will discuss all the things that you need to know before taking home a GLC Benz in 2025.

Mercedes-Benz GLC Overview: What Makes It Special?

The GLC was first introduced in the world market in 2015 and was launched in India the same year. It replaced the old GLK-Class and quickly became the most popular SUV in the Mercedes line-up across the globe. It fits in between the smaller GLA and the three-row GLE.

The GLC has always been a CBU (Completely Built Unit) or CKD (Completely Knocked Down) import in India and sits in the ₹45–70 lakh segment (depending on year and variant). This means that even used Mercedes GLC models have a premium price tag, but also provide more sophistication and comfort than a regular mid-size SUV.

Regardless of whether we are talking about the GLC 220d, the petrol-powered Mercedes GLC 300, or even the older 250 models, the GLC series in itself is famous for:

• Superb NVH levels: Extremely quiet cabins
• Balanced ride quality: Soft yet planted
• Proper AWD in 4MATIC variants: Light off-roading is possible
• Premium interiors: Real wood, dual-zone climate control, sunroof, etc.

Engine Options and Performance

Here’s a quick engine snapshot of what you’re likely to find in the used car market when looking at a used Mercedes GLC:

If you want sheer pace and better city smoothness, the Mercedes GLC 300 petrol makes sense. But for high-mileage users and lower running costs, the 220d diesel with the OM654 engine is one of the most reliable Mercedes tech out there.

Fuel Efficiency and Real-World Mileage

Real-world mileage for used GLCs varies heavily by fuel type and driving conditions. Here’s what you can expect on Indian roads:

• GLC 220d Diesel: 12–15kmpl in mixed use (highway-heavy runs can hit 17+)
• GLC 300 Petrol: 8–11kmpl in city/highway mix
• GLC 300d: 11–13.5kmpl in real-world conditions

It’s important to note that Mercedes cars with older 2.1L diesels (pre-2019 models) tend to be  slightly noisier and consume more fuel.

Ownership Costs & Mercedes Maintenance Cost in India

This is where you’ll want to be prepared. The Mercedes maintenance cost for the GLC is higher than what you’d see for a Toyota Fortuner or even a Skoda Kodiaq, but not as steep as a BMW X3 or Volvo XC60. Here's what you're likely to spend:

• Annual service (basic): ₹40,000–₹60,000
• Major service (every 2 years): ₹70,000–₹90,000 (includes brake fluid, ATF, filters)
• Brake pads and discs: ₹25,000–₹40,000 per axle
• Tyres (19-inch): ₹15,000–₹18,000 per tyre for premium rubber
• Battery (AGM type): ₹18,000–₹25,000; watch out for battery drain issues in pre-2020 cars
• Transmission repairs (if not maintained): ₹1–1.5 lakh

Mercedes offers a Star Ease Service Package even on used cars via dealerships, which is worth it if you plan to keep the car for 3+ years.

Features Checklist: What to Look For in a Used GLC SUV?

Not every used GLC comes with the same kit. Some features were introduced in 2019 and later models only. Here’s a helpful breakdown:

Avoid cars with non-functional infotainment or flickering MID screens, as both are known failure points. Test drive the car at low speed to check for transmission lag, especially in stop-and-go traffic.

What Can Go Wrong?

Here’s the no-fluff list of what to inspect and ask about:

1. Transmission lag or jerks: Check ATF service history. Oil not changed? Walk away.
2. Battery drain problems: GLCs (especially petrol) can kill batteries if unused for 7–10 days. Many users report 3–4 battery replacements in 6–7 years.
3. Sensor errors: Mercedes-Benz electronics are sensitive. An OBD scan is a must before buying.
4. Tyre wear issues: Air suspension GLCs are rare in India, but if equipped, inspect for uneven tyre wear.
5. Parts availability for CBU models: Especially for AMG trims or imported infotainment units and wait times can stretch to 2–3 weeks.

What’s a Fair Price for a Used GLC in India?

Prices vary by city, condition, service history, and whether it’s dealer-certified or not. For the most peace of mind, explore used Mercedes cars from certified CARS24 dealers or MB-certified programmes.

Summary

If you want a proper luxury SUV with no gimmicks, the GLC Benz gets nearly everything right. It’s smooth, refined, reasonably quick, and doesn’t feel dated even after 5 years. Just ensure you pick a post-2019 model for better infotainment and fewer electronic troubles.

It’s not cheap to maintain, but it’s also not too exorbitant if you plan for service costs and avoid cars with dodgy histories. Diesel variants offer better longevity, while petrol is smoother for city runs. In short: A well-kept used Mercedes GLC gives you that ‘Mercedes feel’ without the ₹70 lakh new car hit. But only if you buy smart.
