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

Prices have softened 1.15% compared to this time last year, making it a favorable time to shop this model year.

There are 250 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 — it earns a 5/5 user rating and a 9/10 expert rating. 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 feels like a four-door supercar. It combines serious speed with high-end materials and real-world usefulness, so you get a car that can play both sports car and grand tourer roles.

The trade-offs are clear: all-wheel drive is not available, the ride quality is poor, and a manual transmission is not offered. Even so, the market shows 28.4% of listings as good or great deals, which suggests you may have room to 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 built around a high-performance formula, but it also presents itself as a luxury four-door with surprising practicality. That combination suggests a car engineered to do more than just post big numbers; it is meant to feel usable in everyday driving while still delivering the kind of performance you expect from AMG.

Its performance hardware is extensive, and the expert notes emphasize that it is developed to deliver superior acceleration, braking, ride, and handling qualities. The technology and comfort features also point to a well-equipped ownership experience, including a user-friendly MBUX system and a strong set of available driver-assistance features.

If you buy used, the main long-term risk is that a car built this aggressively can be expensive to keep at its best, 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 81.6% — always verify the vehicle history report.

You should still run a history report on any car you’re considering, even if the listing looks clean. A pre-purchase inspection is especially important here because this is a high-performance luxury model with complex hardware and expensive components. Focus on overall condition, signs of hard use, and whether the car has been maintained consistently.

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 the least expensive way in.
• 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: The Driver Assistance Package adds no fewer than 14 driver-assist features, including Active Emergency Stop Assist, Active Lane Change Assist, Congestion Emergency Braking, adaptive cruise control, and lane-centering assistance.
• Infotainment: MBUX uses two 12.3-inch display screens, and it includes Apple CarPlay, Android Auto, navigation, satellite radio, wireless connectivity, and a wireless charging pad.
• Fuel efficiency: No fuel-economy figure is stated in the available 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 if you want the AMG GT’s style and performance without paying for the upper-end powertrains. It still gives you the core four-door supercar experience, so it makes sense if you care more about the overall package than chasing the fastest version.
• GT 53: This is the best-value trim if you want a stronger balance of performance and everyday usability. It sits above the GT 43 without jumping all the way to the most extreme hardware, so it should suit you if you want a more rounded choice.
• GT 63: This trim is for you if you want a major step up in performance and are willing to pay for it. It moves the car deeper into serious supercar territory while keeping the four-door practicality intact.
• GT 63 S: This is the top performance choice, with the hand-built twin-turbocharged 4.0-liter V8 and the most extreme capability in the lineup. It makes sense if you want the most powerful and most track-focused version.

The Driver Assistance Package is optional, so if safety tech matters to you, make sure the car you’re considering has it equipped.

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

This is a moderate market for selective buyers, so you should shop with a clear target and move quickly on the right car.

• Deal availability: 28.4% of listings are priced as good or great deals.
• Inventory: There are 250 listings available.
• Price trend: Prices have softened 1.15% compared with last year.
• Clean inventory: 81.6% of listings are accident-free.

If you find a listing below $69,964, 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 $77,258 sits slightly below last year's $78,157.

That modest decline suggests the market has softened a bit, which can help you as a buyer today but may also mean future resale gains are limited unless the car is especially well kept. If you plan to sell later, condition and mileage will matter a lot because this is a niche performance model with a narrower buyer pool.

The price range also shows meaningful spread between the low and high ends, so well-optioned or especially clean examples can still command stronger money. 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?

The 2021 Mercedes-Benz AMG GT earns a 10/10 safety score from our experts.

The available Driver Assistance Package adds no fewer than 14 driver-assist features, including adaptive cruise control, lane-centering assistance, Active Emergency Stop Assist, Active Lane Change Assist, Congestion Emergency Braking, and an extended re-start function for stop-and-go traffic.

That package is optional, so you should confirm whether a used example has it before you buy. If safety tech is a priority, it is worth seeking out a car equipped with the package rather than assuming every listing has the same content.

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:

• 28.4% of listings are priced as good or great deals.
• Accident-free inventory is solid at 81.6% — always verify the vehicle history report.
• Price trend: Prices have softened 1.15% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The 2021 stands out as a four-door supercar with serious performance and surprising practicality.

Consider the 2020 if:

• At $78,810, the 2020 costs more than the current year's $77,258 average.
• It is a raw, track-focused exotic that can overwhelm an unskilled driver.

The bottom line: If you want the better-value path, the 2021 is the smarter starting point because it combines a lower average price, strong owner satisfaction, and a broad mix of performance and practicality. If you’re shopping purely for a more intense, old-school exotic feel, the 2020 may appeal more, but you’ll likely pay more for that character.
