Used 2021 Mercedes-Benz AMG GT for SaleNationwide

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

Prices are up 2.99% year-over-year — a sign of continued demand for this model year.

There are 260 listings available, which gives you a modest amount of shopping room.

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

Yes — 5/5 from owners, and the expert rating is 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 feels like a four-door supercar. The overview and test-drive notes both emphasize its blend of serious performance, high-end luxury, and surprising practicality, so it works best if you want one car that can play multiple roles.

The main 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 still shows 28.8% of listings as good or great deals, which suggests there are still worthwhile 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 model’s appeal is reinforced by its strong performance focus and the way it is described as delivering superior acceleration, braking, ride, and handling qualities. It is also presented as a car that can be used comfortably in everyday driving, which matters if you plan to keep it for the long haul.

Its dependability story is tied to the fact that it is engineered with substantial performance hardware and advanced systems, so ownership risk is less about basic competence and more about the complexity that comes with a high-performance luxury car. For used buyers, that means you should expect maintenance discipline to matter.

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

Accident-free inventory is solid at 83.8% — always verify the vehicle history report.

You should still check the history report carefully and prioritize a pre-purchase inspection, especially on a car with this much performance hardware and technology. Focus on condition, maintenance records, and whether the car has been modified or heavily optioned, since those factors can affect both reliability and ownership costs.

Key things to evaluate:

• Trim level: The GT 43, GT 53, GT 63, and GT 63 S each bring meaningful differences 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, a nine-speed multi-clutch automatic, and a performance-tuned AWD system.
• Safety package: The 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.
• Infotainment: The MBUX system uses two 12.3-inch displays, includes Apple CarPlay, Android Auto, navigation, satellite radio, Mercedes Me connected services, near-field communications, and a wireless charging pad.
• Fuel efficiency: The GT 43 accelerates to 60 mph in 4.8 seconds, while the GT 63 S is claimed to do it in 3.1 seconds.

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 least expensive path into the lineup and still gives you the AMG GT’s core style and performance character. It makes the most sense if you want the look and feel without chasing the most extreme output.
• GT 53: This is the best-value trim for most buyers because it should give you a stronger balance of performance and everyday usability than the entry model without jumping all the way to the top-tier price.
• GT 63: This is the step-up choice if you want a more serious performance experience and are willing to pay for it.
• GT 63 S: This is the one for you if you want the most extreme version of the car, with the highest-output hardware and the most track-focused personality.

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

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

This is still a seller’s market, so you should act selectively and be ready to move quickly when the right car appears.

• Deal availability: 28.8% of listings are priced as good or great deals.
• Inventory: There are 260 listings available.
• Price trend: Prices are up 2.99% year-over-year.
• Clean inventory: 83.8% of listings are accident-free.

If you find a listing below $69,979, 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 $77,784 sits slightly above last year's $75,526.

That upward move suggests the market still sees strong appeal in this model year. If you buy well and keep the car in clean condition, you may have a better shot at holding value than with a softer-priced performance car.

The year-round range also matters: cars priced near the low end can create a stronger entry point for future resale if you avoid overpaying now. Strong demand for a distinctive, high-performance luxury car can help support pricing when it’s time to sell.

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

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

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

The Driver Assistance Package is the key safety upgrade to look for, and it adds no fewer than 14 driver-assist features. Standout functions 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 main safety caveat is that this package is optional, so you should confirm whether the car you’re considering has it. If it does not, you may be missing a meaningful layer of driver assistance.

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:

• 28.8% of listings are priced as good or great deals.
• Accident-free inventory is solid at 83.8% — always verify the vehicle history report.
• Price trend: Prices are up 2.99% year-over-year.
• Owners rate it 5/5 — a strong satisfaction signal.
• It combines supercar-style performance with surprising practicality and luxury.

Consider the 2020 if:

• At $80,847, the 2020 costs more than the current year's $77,784 average.
• It feels like a race car first.

The bottom line: The 2021 is the better default choice if you want the strongest mix of performance, luxury, and practicality at a lower average price than the 2020. If you’re shopping mainly on price, the 2020 only makes sense if you find a compelling example with the right equipment and condition.
