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

Prices have softened 5.11% compared to this time last year, making it a favorable time to shop this model year.

There are 234 listings available, which gives you a modest amount of inventory to compare before you buy.

If you find a listing below $69,971.60, that's toward the low end of the year-round range and worth acting on quickly.

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 stands out as a four-passenger, four-door supercar that blends serious performance with luxury and surprising practicality. That makes it a strong fit if you want something that feels special every time you drive it, rather than a conventional grand tourer.

Its strengths are clear: great handling and a powerful engine. The main trade-offs are that all-wheel drive is not available, the ride quality is poor, and a manual transmission is not offered.

With 29.1% of listings marked as good or great deals, 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 2021 Mercedes-Benz AMG GT is presented as a highly engineered performance car that also brings luxury and practicality into the mix. Its expert review emphasizes that it can serve multiple purposes, which usually helps a used buyer feel more confident about day-to-day ownership.

Its performance hardware is extensive, and the expert review describes it as easy to drive in Comfort mode despite its extreme capability. The cost-effectiveness commentary also suggests that the car delivers a lot of substance for the money if you value performance, design, and utility together.

If you buy used, the biggest long-term risk is that a car built around high performance and complex systems 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 83.3% — 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, electronics, and signs of hard use, especially if the car has been driven the way its performance suggests it could be. Pay close attention to cosmetic condition, brake condition, and whether the car feels as tight and composed as it should on the road.

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. The cabin is user-friendly and upscale, but the base setup does not include the more extreme hardware and appearance upgrades found higher up the range.
• Powertrain: The lineup ranges from the GT 43 to the GT 63 S, with the fastest version using a hand-built twin-turbocharged 4.0-liter V8 making 630 horsepower and 664 pound-feet of torque. The GT 43 reaches 60 mph in 4.8 seconds, while the top version is tuned for far more serious performance than most buyers can use on public roads.
• Safety package: A Driver Assistance Package is available and adds no fewer than 14 driver-assist features. Highlights include Active Emergency Stop Assist, extended re-start in traffic, Active Lane Change Assist, and Congestion Emergency Braking.
• Infotainment: The MBUX system uses two 12.3-inch display screens under one piece of glass. It includes Apple CarPlay, Android Auto, satellite radio, navigation, 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 tuned for 3.1-second runs to 60 mph. The expert review does not provide mpg figures.

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:

• Base trim: The GT 43 gives you the entry point to the lineup, but you give up the more extreme power and performance available higher up the range.
• Sweet-spot trim: The GT 53 is the best balance if you want strong performance without jumping all the way to the most expensive versions.
• Premium/top trim: The GT 63 S is the most compelling choice if you want the full performance experience, including the hand-built twin-turbo V8 and the most aggressive tuning.
• Off-road trim: Not applicable here.

The Driver Assistance Package is available, and it adds 14 driver-assist features that are worth considering if you want more everyday safety support.

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: 29.1% of listings are priced as good or great deals.
• Inventory: There are 234 listings available.
• Price trend: Prices have softened 5.11% compared with last year.
• Clean inventory: 83.3% of listings are accident-free.

If you find a listing below $69,971.60, 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 $74,367 sits slightly below last year's $78,369.

That price movement suggests the market has eased a bit, which can help you buy more confidently now. For a future seller, it also means you should expect resale value to depend heavily on condition, mileage, and how well the car has been maintained.

Because this model year combines strong performance with luxury and practicality, well-kept examples should continue to attract interest 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.

A Driver Assistance Package is available, and it adds 14 driver-assist features. Standout items include 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 a meaningful upgrade if you want more everyday protection and convenience, especially in traffic. If you shop a used example, confirm whether that package is installed, since it is not standard on every car.

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:

• 29.1% of listings are priced as good or great deals.
• Accident-free inventory is solid at 83.3% — always verify the vehicle history report.
• Price trend: Prices have softened 5.11% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• It combines serious performance with surprising practicality in a four-passenger, four-door package.

Consider the 2020 if:

• At $83,729, the 2020 costs more than the current year's $74,367 average.
• It is a raw, razor-sharp sports car built around motorsport heritage.

The bottom line: If you want the better value proposition, the 2021 is the smarter starting point because it has softened in price while still delivering the model’s core appeal. If your priority is a more extreme, race-car-like character and you are willing to pay more, the 2020 may be the better emotional fit.
