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 car that emphasizes style and performance while still offering some practicality. The overview describes it as a four-door supercar that can serve multiple purposes, and the expert review backs that up with strong luxury and usability notes alongside its performance focus.

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 31.9% 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 overview presents this AMG GT as a car that can do more than one job, and the expert review reinforces that it is built with substantial performance hardware and a high level of refinement. The performance write-up also emphasizes that the car is engineered for superior acceleration, braking, ride, and handling qualities, which points to a well-developed package rather than a compromised one.

The tech and safety equipment are substantial, and the car’s premium positioning suggests it was built with durability and sophistication in mind. For used buyers, the main long-term risk is that ownership costs and complexity can be high if the car has been neglected or modified.

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

Accident-free inventory is solid at 81.2% — always verify the vehicle history report.

You should still run a history report on every candidate, because a clean listing percentage does not replace documentation. Prioritize a pre-purchase inspection that focuses on the drivetrain, brakes, suspension, and electronics, since this is a high-performance luxury car with a lot of specialized hardware. Pay close attention to overall condition, because wear, repairs, and missing equipment can matter more here than on a mainstream sedan.

Key things to evaluate:

• Trim level: The lineup includes GT 43, GT 53, GT 63, and GT 63 S. The GT 43 and GT 53 are the more sensible choices, while the GT 63 S is the most extreme and expensive version.
• Powertrain: The car is offered with multiple powertrains, and the fastest version uses a hand-built twin-turbocharged 4.0-liter V8 with 630 horsepower and 664 pound-feet of torque. The performance write-up also notes that the GT 43 accelerates to 60 mph in 4.8 seconds.
• 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, Congestion Emergency Braking, and an extended re-start function. It was not standard on the test vehicle.
• Infotainment: The MBUX system uses two 12.3-inch display screens, and it includes Apple CarPlay, Android Auto, satellite radio, navigation, wireless connectivity, and a wireless charging pad.
• Fuel efficiency: No MPG or MPGe 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, and it makes the most sense if you want the AMG GT experience without chasing the most extreme performance. It is the least expensive way into the lineup and still delivers the car’s core style and capability.
• GT 53: This is the best-value trim for many shoppers because it sits above the base version while staying short of the most expensive performance models. It should be the trim to focus on if you want a stronger balance of performance and everyday usability.
• GT 63: This trim is for you if you want a bigger step up in performance and are willing to pay for it. It moves the car deeper into high-performance territory.
• GT 63 S: This is the top-performance choice, and the expert review makes clear that it is overbuilt for public roads. Buy it only if you specifically want the most extreme version and can use its hardware.

The Driver Assistance Package is optional, so check whether a used example 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 can shop with some leverage if you stay patient.

• Deal availability: 31.9% of listings are priced as good or great deals.
• Inventory: There are 276 listings available.
• Price trend: Prices are up 5.10% year-over-year.
• Clean inventory: 81.2% of listings are accident-free.

If you find a listing below $69,791, 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 $78,316 sits slightly above last year's $74,517.

That year-over-year increase suggests the market has held up reasonably well for this model year. For a future seller, that can be a positive sign because stronger current pricing often reflects steady demand rather than a softening market.

The fact that prices are still within a defined year-round range also gives you a useful benchmark for timing your sale. If you bought well and kept the car in strong condition, you may be able to preserve value better than with a less desirable performance car.

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.

A Driver Assistance Package is available, and it 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, Congestion Emergency Braking, and an extended re-start function for stop-and-go traffic.

The package is optional, so you should confirm whether a used example has it. If safety equipment matters to you, that should be near the top of your checklist.

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:

• 31.9% of listings are priced as good or great deals.
• Accident-free inventory is solid at 81.2% — always verify the vehicle history report.
• Price trend: Prices are up 5.10% year-over-year.
• Owners rate it 5/5 — a strong satisfaction signal.
• Mercedes describes it as a four-door supercar that blends performance, luxury, and practicality.

Consider the 2020 if:

• At $81,476, the 2020 costs more than the current year's $78,316 average.
• It is a raw, razor-sharp exotic sports car built for track intent.

The bottom line: The 2021 is the better all-around pick if you want the newer market position, stronger value context, and the same dramatic AMG GT character. If you are shopping strictly on price, the 2020 can still appeal, but the 2021 gives you a more compelling balance of demand, satisfaction, and used-market availability.
