Used 2021 Mercedes-Benz AMG GT for Sale near Connecticut

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 249 listings available, which gives you a modest pool to compare before you buy.

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

Yes — it earns a 5/5 from owners and a 9/10 expert rating. The model scores 10/10 across Performance and Safety.

The overview frames it as a four-passenger, four-door supercar that blends serious performance with luxury and surprising practicality. That lines up with the expert notes, which praise its strong handling, powerful engine, and ability to feel like multiple vehicles in one.

The main trade-offs are clear: all-wheel drive is not available, the ride quality is poor, and a manual transmission is not offered. If you want a high-performance luxury car that still works as a usable four-door, this setup makes sense.

Good and great deals account for 28.1% of listings, so you have some room to shop selectively.

Is the 2021 Mercedes-Benz AMG GT reliable?

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

The overview and expert notes both point to a car that is engineered to deliver a high level of performance without giving up everyday usability. The expert commentary also emphasizes that it can be driven comfortably in normal conditions, which matters if you plan to use it regularly.

Its performance hardware and refined driving character suggest a well-developed package, and the cost-effectiveness notes reinforce that it is built to serve multiple purposes rather than just one. If you buy used, the main long-term risk is that a complex, high-performance car can be expensive to keep at its best.

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 still check the history report carefully, because a clean listing percentage does not replace documentation. Prioritize a pre-purchase inspection that focuses on wear items, signs of hard driving, and whether the car has been maintained consistently. Pay close attention to overall condition, since this is a performance-focused luxury car where neglected maintenance can matter more than on a mainstream sedan.

Key things to evaluate:

• Trim level: The GT 43, GT 53, GT 63, and GT 63 S each step up in power and performance, with the GT 43 positioned as the entry point and the GT 63 S as the most extreme version.
• Powertrain: The lineup includes substantial performance upgrades, and the GT 63 S uses a hand-built twin-turbocharged 4.0-liter V8 with a nine-speed multi-clutch automatic transmission and performance-tuned AWD.
• 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, and Congestion Emergency Braking.
• Infotainment: The MBUX system uses two 12.3-inch displays, includes Apple CarPlay and Android Auto, and supports wireless connectivity; augmented reality navigation is available.
• 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, and it makes the most sense if you want the AMG GT experience without chasing the most extreme performance. It still gives you the car’s core style, luxury, and usability.
• GT 53: This is the best-value trim if you want a stronger balance of performance and everyday livability. It should suit you if you want more punch than the GT 43 without jumping all the way to the top end.
• GT 63: This 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 “the best.”
• GT 63 S: This is the most extreme choice, with the strongest performance focus and the most serious hardware. It suits you if you want the top-spec version and plan to exploit its capability.

The Driver Assistance Package is optional, so if safety tech matters to you, look for a car equipped with it.

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

This is a moderate market for selective buyers, so it makes sense to shop carefully and compare listings.

• Deal availability: 28.1% of listings are priced as good or great deals.
• Inventory: There are 249 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 $69,964, 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 $77,380 sits slightly above last year's $76,979.

That small increase suggests the market has stayed relatively stable, which is helpful if you plan to resell later. A steady price pattern can make it easier to estimate future value because the model is not showing sharp swings in either direction.

The current inventory and deal mix also suggest that buyers are still paying attention to this car, especially when the right trim or condition shows up. 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 Driver Assistance Package is optional, 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, extended re-start in stop-and-go traffic, and Congestion Emergency Braking.

That package is worth seeking out if safety tech matters to you, especially because it is not standard on the test vehicle described here. The provided safety notes do not mention any crash-test shortcoming, so the main safety takeaway is that the available driver-assistance suite is extensive.

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:

• 28.1% 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.
• It combines serious performance with surprising practicality in a four-door supercar package.

Consider the 2020 if:

• At $78,858, the 2020 costs more than the current year's $77,380 average.
• It is described as a raw, razor-sharp, track-focused exotic with a serious edge.

The bottom line: The 2021 is the better primary target if you want the strongest mix of performance, luxury, and everyday usability at a slightly lower average price. If you are shopping mainly on price, the 2020 can still appeal for its more intense, race-car-first character, but the 2021 is the more balanced buy.
