Used 2021 Mercedes-Benz AMG GT for SaleNationwide

How much does the 2021 Mercedes-Benz AMG GT cost?

Prices have held steady compared to this time last year, signaling a stable and predictable market for this model year.

There are 243 listings available, which gives you a modest amount of inventory to compare before you buy.

Is the 2021 Mercedes-Benz AMG GT a good car?

Yes — you’re looking at a 5/5 user-rated car with an expert rating of 9/10. The model scores 10/10 across Performance and Safety.

The 2021 Mercedes-Benz AMG GT is aimed at you if you want a four-passenger luxury performance car that blends serious speed with surprising practicality. The overview frames it as a four-door supercar, and the expert notes back that up with strong handling, a powerful engine, and a cabin that still works for everyday use.

The trade-offs matter, though: the ride quality is poor, all-wheel drive is not available, and a manual transmission is not offered. Even so, the market shows 32.5% of listings as good or great deals, which suggests there are still attractive opportunities if you shop carefully.

Is the 2021 Mercedes-Benz AMG GT reliable?

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

The 2021 Mercedes-Benz AMG GT is presented as a high-performance machine that still manages to be usable in daily driving, which is a good sign for ownership confidence if you value a car that feels special without being unusable. The expert notes emphasize strong acceleration, refined road manners in Comfort mode, and a car that can be driven without constantly feeling harsh or unruly.

Its performance hardware is extensive, and the expert write-up highlights a well-developed chassis, braking, and suspension setup that supports both speed and everyday composure. The cost-effectiveness notes also point to a car that delivers multiple roles in one package, which can make ownership feel more rewarding if you want one vehicle to cover several needs.

If you buy used, the main long-term risk is that a highly specialized performance car can be expensive to keep in top shape, so condition and maintenance history matter a lot.

What should I look for when buying a used 2021 Mercedes-Benz AMG GT?

Accident-free inventory is solid at 81.1% — always verify the vehicle history report.

You should start with a vehicle history report and then prioritize a pre-purchase inspection from a shop that knows high-performance Mercedes models. Focus on signs of hard use, uneven wear, and any evidence that the car has been driven more aggressively than its mileage might suggest.

Key things to evaluate:

• Trim level: The GT 43, GT 53, GT 63, and GT 63 S each bring substantial increases in power and performance, and the base version is still positioned as a serious luxury-performance car rather than a stripped-down entry model.
• Powertrain: The lineup ranges from the GT 43 to the GT 63 S, with the top version using a hand-built twin-turbocharged 4.0-liter V8 and a nine-speed multi-clutch automatic transmission.
• Safety package: A Driver Assistance Package is available and adds no fewer than 14 driver-assist features, including adaptive cruise control, lane-centering assistance, Active Emergency Stop Assist, Active Lane Change Assist, and Congestion Emergency Braking.
• Infotainment: The MBUX system uses two 12.3-inch display screens, includes Apple CarPlay and Android Auto, and supports wireless connectivity plus a wireless charging pad.
• Fuel efficiency: No fuel-economy figure is stated in the provided data.

Which 2021 Mercedes-Benz AMG GT trim should I buy?

The 2021 Mercedes-Benz AMG GT is offered in 4 trim levels: GT 43, GT 53, GT 63, GT 63 S.

Here's the short version:

• GT 43: This is the entry point, but it still gives you the AMG GT 4-Door Coupe’s core appeal: dramatic styling, four-seat practicality, and serious performance. It makes the most sense if you want the look and feel of the car without chasing the highest-output versions.
• GT 53: This is the best-value trim for most buyers because it sits above the base model without pushing all the way into the most extreme pricing and performance territory. It should suit you if you want a stronger balance of speed, luxury, and everyday usability.
• GT 63: This trim is for you if you want a major step up in performance and are willing to pay for it. The expert notes make clear that the higher trims are aimed at buyers who want more than they can realistically use on public roads.
• GT 63 S: This is the top-performance choice, with the hand-built twin-turbo V8 and the most extreme acceleration and track-focused capability in the lineup. It suits you best if outright performance is the priority and price is secondary.

A Driver Assistance Package is available, and it adds a broad set of safety and convenience features across the lineup.

Is now a good time to buy a used 2021 Mercedes-Benz AMG GT?

This looks like a moderate, selective buyer’s market, so you can shop with some leverage if you’re patient.

• Deal availability: 32.5% of listings are priced as good or great deals.
• Inventory: There are 243 listings available.
• Price trend: Prices have held steady compared with last year.
• Clean inventory: 81.1% of listings are accident-free.

If you find a listing below $69,972, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2021 Mercedes-Benz AMG GT's resale value?

The current average of $76,750 sits slightly above last year's $76,336.

That small increase suggests the market has stayed relatively stable, which is helpful if you’re thinking about future resale. A steady price trend can make it easier to estimate what your car may be worth later, especially if you keep mileage and condition in check.

Because the model sits in a niche performance-luxury space, well-kept examples should continue to attract attention from shoppers who want something distinctive. Vehicles with strong owner satisfaction ratings, like this model year's 5/5, tend to retain buyer demand, which supports resale value over time.

Is the 2021 Mercedes-Benz AMG GT safe?

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

The AMG GT 4-Door Coupe offers an available Driver Assistance Package that adds no fewer than 14 driver-assist features. Standout items include adaptive cruise control, lane-centering assistance, Active Emergency Stop Assist, Active Lane Change Assist, extended re-start functionality in traffic, and Congestion Emergency Braking.

The package is optional, so you should confirm whether a used example has it before you buy. If safety tech matters to you, that option is worth prioritizing because it meaningfully expands the car’s active-safety capability.

Should I buy a 2021 Mercedes-Benz AMG GT or consider a different year?

If you're weighing the 2021 against nearby model years, here's how to think about it:

Choose the 2021 if:

• 32.5% of listings are priced as good or great deals.
• Accident-free inventory is solid at 81.1% — always verify the vehicle history report.
• Price trend: Prices have held steady compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The 2021 stands out as a four-door supercar with strong handling, a powerful engine, and real everyday usability.

Consider the 2020 if:

• At $79,489, the 2020 costs more than the current year's $76,750 average.
• It is a raw, track-focused exotic that can overwhelm an unskilled driver.

The bottom line: If you want the better-balanced buy, the 2021 is the stronger path because pricing is steadier, inventory is available, and the car combines performance with practicality. If you’re shopping strictly for a more intense, old-school exotic feel and don’t mind paying more, the 2020 may still appeal.
