Used 2021 Mercedes-Benz AMG GT for Sale nearChicago, IL

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

Prices have softened 2.47% compared to this time last year, making it a favorable time to shop this model year.

There are 244 listings available, which gives you a modest amount of inventory to compare before you buy.

If you find a listing below $69,978.62, 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 — the 5/5 user rating and 9/10 expert rating point to a model that delivers strongly for the right buyer. The 2021 Mercedes-Benz AMG GT is framed as a four-door supercar that blends serious performance with luxury and surprising practicality, so you get a car that can serve more than one role.

The model scores 10/10 across Performance and Safety.

Its strengths are clear: great handling, a powerful engine, and a cabin that can carry four adults with usable cargo space. The trade-offs are just as clear: all-wheel drive is not available, the ride quality is poor, and a manual transmission is not offered.

With 28.3% of listings marked as good or great deals, you have some room to shop selectively if you want the right mix of performance and price.

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 capable, well-engineered performance car that also brings luxury and practicality into the mix, which usually helps ownership feel rewarding when the car is maintained properly.

Its performance hardware is extensive, and the expert review emphasizes that it is built to deliver superior acceleration, braking, ride, and handling qualities. The cost-effectiveness commentary also suggests that you get a lot of capability and versatility for the money, especially if you value the car’s blend of sports-car and luxury-car traits.

If you buy used, the main long-term risk is that a complex high-performance setup 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 83.2% — always verify the vehicle history report.

You should still check the history report carefully, because a clean title alone does not tell you how the car was driven or maintained. Prioritize a pre-purchase inspection that focuses on wear from performance use, especially brakes, tires, suspension, and any signs of cosmetic or curb damage. You should also pay close attention to whether the car’s condition matches its mileage and asking price.

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 one most likely to leave you wanting more if you care about outright pace.
• Powertrain: The lineup ranges from the slower GT 43 to the hand-built twin-turbocharged 4.0-liter V8 in the GT 63 S, which delivers massive output and a claimed 3.1-second sprint to 60 mph.
• 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, and Congestion Emergency Braking.
• 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 here.

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 with the least extreme performance focus. It still gives you the car’s style, luxury, and practicality, but it is the least powerful version in the lineup.
• GT 53: This is the best-value trim for most shoppers because it sits in the middle of the range and is described as a more sensible selection than the top versions. It should give you a strong balance of performance and everyday usability without pushing into the most expensive territory.
• GT 63: This is the step-up choice if you want a more serious performance edge and are willing to pay for it. It suits you if you want more of the AMG character without going all the way to the most extreme version.
• GT 63 S: This is the one for you if you want the most power and the most dramatic performance. The expert review makes clear that it is overbuilt for public roads and best suited to buyers who truly want the top hardware.

A Driver Assistance Package is available, and it adds a broad set of safety and convenience features if you want more driver support.

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

This is a moderate, selective buyer’s market, so you can shop carefully and still find opportunities.

If you find a listing below $69,978.62, 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 $76,683 sits slightly below last year's $78,623.

That price movement suggests the market has eased a bit, which can help you buy more selectively now. For a future seller, the softer trend means you should expect resale value to depend heavily on condition, mileage, and trim choice rather than assuming the car will hold its price automatically.

Because this model has strong enthusiast appeal and a high satisfaction rating, well-kept examples should continue to attract buyers. That helps support resale value over time, especially for desirable trims and clean-history cars.

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 installs 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 capability in stop-and-go traffic, and Congestion Emergency Braking.

The package is a meaningful upgrade if you want more everyday protection and convenience in a high-performance car. If you are shopping used, make sure the specific car you are considering actually has this package, because it was optional.

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:

• 28.3% of listings are priced as good or great deals.
• Accident-free inventory is solid at 83.2% — always verify the vehicle history report.
• Price trend: Prices have softened 2.47% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• Mercedes describes it as a four-door supercar with serious performance and surprising practicality.

Consider the 2020 if:

• At $82,824, the 2020 costs more than the current year's $76,683 average.
• It is a raw, razor-sharp sports car built around motorsport heritage.

The bottom line: If you want the stronger value proposition, the 2021 is the better starting point because prices have eased and inventory is available. If your priority is a more extreme, old-school sports-car feel and you are willing to pay more for it, the 2020 may still appeal.
