Used 2020 Mercedes-Benz GLC for Sale near Illinois

How much does the 2020 Mercedes-Benz GLC cost?

Prices have softened 11.10% compared to this time last year, making it a favorable time to shop this model year.

With 1,821 listings available, you have a solid amount of inventory to compare before you buy.

If you find a listing below $22,919.02, that's toward the low end of the year-round range and worth acting on quickly.

Is the 2020 Mercedes-Benz GLC a good car?

Yes — the 4.77/5 user rating points to strong owner satisfaction, and the expert rating is 7.33/10. The standout strength is Safety at 10/10.

Owners consistently praise the GLC for its luxury features, comfort, quick acceleration, and value for money. The all-wheel-drive setup also comes up as a plus for winter driving, which fits the GLC’s appeal as a premium compact crossover for suburban use.

The trade-offs are clear: the base GLC 300’s performance is a weak point, and the back seat is cramped. Even so, the model’s upscale cabin, technology, and broad powertrain range make it a compelling choice if you want a polished luxury SUV rather than a sporty one.

With 33.1% of listings marked as good or great deals, there are still worthwhile opportunities in the market.

Is the 2020 Mercedes-Benz GLC reliable?

Owners rate it 4.77/5, a strong signal of long-term satisfaction.

The owner feedback points to a vehicle that feels dependable in daily use, with praise for comfort, value, and all-wheel-drive confidence that helps you count on it in winter conditions. The expert evaluation also describes the GLC as a well-equipped, polished luxury crossover that should suit buyers looking for a premium vehicle they can live with every day.

The ownership picture is helped by standard connected services and a well-rounded feature set, which can make the car feel easier to use and maintain over time. Still, used buyers should plan for the usual luxury-SUV ownership risks, especially if the vehicle has been driven hard or maintained inconsistently.

What should I look for when buying a used 2020 Mercedes-Benz GLC?

At 74.8% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle-history report and then prioritize a pre-purchase inspection, especially on cars with higher mileage or incomplete service records. Focus on body condition, signs of prior repair, and whether the electronics and driver-assistance features work as intended.

Key things to evaluate:

• Trim level: The standard GLC 300 is the most mainstream choice, while AMG versions add much more visual drama with wider tires, a vertical-bar grille, and a lower stance. The base model is the one most likely to leave you wanting more style.
• Powertrain: The GLC 300 uses a turbocharged inline 4-cylinder with 255 horsepower and a 9-speed automatic, with rear-wheel drive or 4Matic all-wheel drive depending on configuration. The AMG models bring much stronger V6 or V8 performance, but the standard engine is the one most buyers will encounter.
• Safety package: The standard suite includes forward emergency braking, Exit Warning Assist, Pre-Safe Sound, and Predictive Brake Priming. The GLC also earned top crash-test marks, but you should confirm that the safety systems are functioning properly.
• Infotainment: You get a standard 10.3-inch touchscreen, Apple CarPlay, Android Auto, and USB-C ports. The 12.3-inch display is available for the instrument cluster, and augmented-reality navigation is offered with the optional navigation system.
• Fuel efficiency: The GLC 300 4Matic is EPA-rated at 21 mpg city, 28 highway, and 24 combined. The AMG GLC 63 models are estimated at 16/22/18.

Which 2020 Mercedes-Benz GLC trim should I buy?

The 2020 Mercedes-Benz GLC is offered in 4 trim levels: GLC 300, GLC 300 Coupe, AMG GLC 43, AMG GLC 63.

Here's the short version:

• GLC 300: This is the trim most buyers should start with because it delivers the core GLC experience at the lowest entry point. You get the standard 10.3-inch touchscreen, MBUX, heated front seats, LED headlights, and the broadest everyday usefulness without stepping into AMG pricing.
• GLC 300 Coupe: Choose this if you care more about style than maximum practicality. It costs more than the regular GLC 300, but the fastback shape gives you a more distinctive look.
• AMG GLC 43: This is the performance-oriented sweet spot if you want a much stronger engine without jumping all the way to the top AMG model. It suits you if you value speed and a more exciting drive over value.
• AMG GLC 63: Pick this only if you want the most extreme performance in the lineup. It brings the most power and the most expensive price tag, so it makes sense mainly for buyers who are prioritizing performance above all else.

The safety package is a major strength across the lineup, and the GLC’s top crash-test results make even the lower trims feel well protected.

Is now a good time to buy a used 2020 Mercedes-Benz GLC?

This is a moderate, selective buyer’s market, so you can shop carefully and still find worthwhile deals.

• Deal availability: 33.1% of listings are priced as good or great deals.
• Inventory: There are 1,821 listings available.
• Price trend: Prices have softened 11.10% compared with last year.
• Clean inventory: 74.8% of listings are accident-free.

If you find a listing below $22,919.02, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2020 Mercedes-Benz GLC's resale value?

The current average of $23,037 sits slightly below last year's $25,914.

That price movement suggests the GLC has already absorbed a meaningful amount of depreciation, which can help future sellers if they buy at the right price. A softer market today can also mean less room for appreciation later, so condition and mileage matter more when you think about eventual resale.

If you keep the vehicle well maintained and avoid accident history, you improve your odds of holding value better than average. Strong feature content and broad buyer appeal should continue to support demand.

Vehicles with strong owner satisfaction ratings, like this model year's 4.77/5, tend to retain buyer demand, which supports resale value over time.

Is the 2020 Mercedes-Benz GLC safe?

The GLC was named a 2019 Top Safety Pick+ by the Insurance Institute for Highway Safety (IIHS), and the National Highway Traffic Safety Administration (NHTSA) gave it five-star ratings in all crash tests.

It earns a 10/10 safety score from our experts.

The standard safety setup includes forward emergency braking, Exit Warning Assist, Pre-Safe Sound, and Predictive Brake Priming. Exit Warning Assist is a useful addition for urban parking situations because it can warn you about approaching cyclists or cars after shutdown.

The main caveat is that some of the GLC’s most advanced safety and convenience features are part of the broader tech package rather than universally standard across every configuration, so you should verify the exact equipment on any used example you’re considering.

Should I buy a 2020 Mercedes-Benz GLC or consider a different year?

If you're weighing the 2020 against nearby model years, here's how to think about it:

Choose the 2020 if:

• 33.1% of listings are priced as good or great deals.
• At 74.8% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 11.10% compared with last year.
• Owners rate it 4.77/5 — a strong satisfaction signal.
• The 2020 brings a standard 10.3-inch touchscreen and updated safety tech.

Consider the 2021 if:

• At $26,354, the 2021 costs more than the current year's $23,037 average.
• It adds a more refined, tech-forward compact luxury SUV experience.

The bottom line: If you want the better value, the 2020 is the smarter buy because prices are softer and the feature set is still strong. If you’re willing to spend more for the newer model year, the 2021 is the better path for shoppers who want the latest iteration and don’t mind paying extra for it.
