How much does the 2021 BMW M4 cost?

Prices have held steady compared to this time last year, signaling a stable and predictable market for this model year.

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

Is the 2021 BMW M4 a good car?

Yes — the 5/5 user rating and 7.5/10 expert rating point to a car that delivers strongly for the right buyer. The standout strength is Performance at 10/10.

The 2021 BMW M4 is built for drivers who care as much about the experience as the destination, and its powerful engine plus available manual transmission make it especially appealing if you want a more involved drive. The trade-offs are clear: poor ride quality and poor fuel economy, along with a cramped back seat, mean it is not the most comfortable or practical daily choice.

The 34.0% good-or-great-deal share suggests there are still worthwhile listings to find if you shop carefully.

Is the 2021 BMW M4 reliable?

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

The 2021 BMW M4 is presented as a focused performance car with strong driving appeal, and the expert evaluation emphasizes how smooth and eager the twin-turbo inline-six feels. It also notes that the manual transmission is easy to manage in traffic, which helps the car feel less demanding than many high-performance coupes.

The performance write-up also points to robust hardware such as structural bracing, track-ready cooling systems, an electrically controlled exhaust, forged lightweight wheels, adaptive M suspension, and M compound brakes, all of which support durability in hard use. BMW also describes the engine as smooth and eager, which is a good sign for everyday drivability.

For used buyers, the main long-term risk is that this kind of performance car may have been driven hard, so condition and maintenance history matter more than mileage alone.

What should I look for when buying a used 2021 BMW M4?

Accident-free inventory is solid at 79.5% — always verify the vehicle history report.

You should still check the vehicle history report carefully, because a performance coupe like this may have seen spirited use. Prioritize a pre-purchase inspection that focuses on the brakes, suspension, steering, and any signs of aftermarket modification. You should also pay close attention to overall condition, since the car’s appeal depends heavily on how well it has been maintained.

Key things to evaluate:

• Trim level: The standard M4 comes with a six-speed manual gearbox and rear-wheel drive, while the M4 Competition adds an eight-speed automatic and extra power. The base car is the one to focus on if you want the manual driving experience, while the Competition suits you if you want more power and an automatic.
• Powertrain: The standard car uses a twin-turbocharged 3.0-liter inline-six with 473 horsepower and 406 pound-feet of torque. The engine is described as smooth and eager, and the manual gearbox is praised for its positive engagement.
• Safety package: The M4 Competition offers the Driving Assistance Professional Package, which includes adaptive cruise control with stop-and-go capability, lane-centering assistance, evasive-steering assistance, active blind-spot protection, and extended traffic-jam assistant technology. The manual-transmission car lacks several driver-assist features that require the Competition’s automatic transmission.
• Infotainment: Standard equipment includes Apple CarPlay, Android Auto, satellite radio, navigation, connected services, and a Harman Kardon premium surround-sound audio system. The Executive Package adds a WiFi hotspot, wireless smartphone charging, gesture control, and a head-up display.
• Fuel efficiency: The expert evaluation says fuel economy is poor, and it notes an observed 20.2 mpg on the test loop versus an official 19 mpg combined estimate.

Which 2021 BMW M4 trim should I buy?

The 2021 BMW M4 is offered in 2 trim levels: M4 and M4 Competition.

Here's the short version:

• M4: This is the one to choose if you want the manual transmission and the most involved driving experience. It keeps the car’s core appeal intact and is the better fit if you value driver engagement over extra power and automatic convenience.
• M4 Competition: This is the better choice if you want more power and an eight-speed automatic. It also unlocks the available Driving Assistance Professional Package, so it suits you if you want the strongest performance and the most advanced driver-assistance tech.

The manual-transmission M4 lacks several driver-assist features that require the Competition’s automatic transmission.

Is now a good time to buy a used 2021 BMW M4?

This looks like a moderate, selective buyer’s market, so you can shop patiently but still move quickly on the right car.

• Deal availability: 34.0% of listings are priced as good or great deals.
• Inventory: There are 244 listings available.
• Price trend: Prices have held steady compared with last year.
• Clean inventory: 79.5% of listings are accident-free.

If you find a listing below $63,512, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2021 BMW M4's resale value?

The current average of $64,737 sits slightly below last year's $65,269.

That small decline suggests the market has softened a bit, but not dramatically. For a future seller, that usually means you should expect steady demand rather than a sharp appreciation story. Well-kept examples should still attract attention because the model’s enthusiast appeal remains strong.

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 BMW M4 safe?

The 2021 BMW M4 does not have crash-test ratings listed here.

It earns a 7/10 safety score from our experts.

The M4 Competition offers the Driving Assistance Professional Package, which includes adaptive cruise control with stop-and-go capability, lane-centering assistance, evasive-steering assistance, active blind-spot protection, and extended traffic-jam assistant technology. The standard M4 still includes blind-spot monitoring, rear cross-traffic alert, lane-departure warning, speed-limit recognition, front and rear collision-preparation systems, and post-collision braking.

One important caveat is that the manual-transmission M4 lacks several driver-assist features that require the Competition’s automatic transmission.

Should I buy a 2021 BMW M4 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:

• 34.0% of listings are priced as good or great deals.
• Accident-free inventory is solid at 79.5% — 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 pairs a powerful engine with a manual transmission for a more involved driving experience.

Consider the 2022 if:

• At $69,580, the 2022 costs more than the current year's $64,737 average.
• It adds xDrive all-wheel drive to the top-spec Competition for better torque delivery.

The bottom line: If you want the best mix of price stability, enthusiast appeal, and manual-transmission involvement, the 2021 is the smarter buy. If you are willing to spend more for all-wheel drive and newer-model-year upgrades, the 2022 is the better path. For price-sensitive buyers, the 2021 offers the stronger value story.
