Used 2021 BMW M3 for Sale nearBoston, MA

How much does the 2021 BMW M3 cost?

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

There are 117 listings available, which suggests a fairly limited pool of inventory for shoppers.

Is the 2021 BMW M3 a good car?

It is a strong choice if you want a luxury performance sedan that prioritizes driving excitement over comfort, and the numbers back that up with a 3.67/5 user rating and a 6.67/10 expert rating. The standout strength is Performance at 10/10.

The test-drive notes describe it as a car that can feel calm when you want it to and ferocious when you do not, with a powerful engine, a manual transmission available, and sharp responses that make it especially appealing if you want a genuinely engaging sedan. The main trade-offs are poor ride quality and not much cargo space, so you are giving up some everyday polish for the payoff in speed and driver involvement.

That balance makes the M3 best suited to you if you want a usable four-door that still feels special on a back road or track day. 29.9% of listings are priced as good or great deals, which gives you some room to shop selectively.

Is the 2021 BMW M3 reliable?

The 2021 BMW M3 is built around a high-performance formula, so its long-term appeal depends on how much you value driving excitement versus ownership simplicity. The expert notes emphasize that it is engineered for serious performance, with cooling attention for the engine, oil, turbocharger, and brakes, and the performance exhaust can be tuned quieter when you want it to be.

The performance notes also point to a car that rewards smooth, measured driving and can feel like it might bite if you make sudden inputs, which is a useful reminder that this is a demanding machine rather than a relaxed commuter. For used buyers, that means your biggest long-term risk is buying a hard-driven example that has been maintained poorly or used beyond its intended comfort zone.

What should I look for when buying a used 2021 BMW M3?

Accident-free inventory is solid at 76.1% — 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 from spirited driving, and pay close attention to the condition of the brakes, tires, suspension, and interior trim.

Key things to evaluate:

• Trim level: The base car gives you the manual transmission and the core performance setup, while the Competition version adds more power and an automatic transmission. The base trim is the better fit if you want the manual and a more involved driving experience, while the Competition suits you if you want the quicker, more aggressive setup.
• Powertrain: The standard car uses a twin-turbocharged 3.0-liter inline six with 473 horsepower and 406 pound-feet of torque, while the Competition version raises output to 503 hp and 479 lb-ft. The standard car uses a six-speed manual, and the Competition uses an eight-speed automatic.
• Safety package: BMW includes forward-collision warning, automatic emergency braking, lane-departure warning, lane-keeping assistance, blind-spot warning, rear cross-traffic warning, drowsy driver monitoring, post-crash braking, and BMW Assist eCall with an SOS button and automatic collision notification. The Driving Assistance Professional Package is available only on the Competition model.
• Infotainment: The M3 uses iDrive 7.0 with a touchscreen and voice recognition, plus Apple CarPlay and Android Auto. The system is quick to respond, and the voice controls work especially well.
• Fuel efficiency: The test-drive notes say fuel economy drops by 7 mpg to 19 mpg in combined driving.

Which 2021 BMW M3 trim should I buy?

The 2021 BMW M3 is offered in 2 trim levels: M3 and M3 Competition.

Here's the short version:

• M3: This is the one to buy if you want the manual transmission and the most direct, old-school driver involvement. It delivers the core M3 experience with 473 horsepower, rear-wheel drive, and the six-speed manual, making it the best-value choice for enthusiasts who care most about engagement.
• M3 Competition: Choose this if you want the quicker, more aggressive setup and do not mind giving up the manual. It adds 503 hp, an eight-speed automatic, and stronger straight-line performance, so it suits you best if maximum pace matters more than shifting for yourself.

BMW’s Driving Assistance Professional Package is only available on the Competition model.

Is now a good time to buy a used 2021 BMW M3?

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

• Deal availability: 29.9% of listings are priced as good or great deals.
• Inventory: There are 117 listings available.
• Price trend: Prices have held steady compared with last year.
• Clean inventory: 76.1% of listings are accident-free.

If you find a listing below $67,260, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2021 BMW M3's resale value?

The current average of $69,898 sits slightly below last year's $70,329.

That small decline suggests the market has softened a bit, but not dramatically. For you as a future seller, that means the M3 is holding value reasonably well for a performance sedan, especially given its niche appeal and enthusiast demand.

Because the price range has stayed fairly tight, condition and equipment will matter a lot when you go to sell. A well-kept example with desirable features should be easier to move than one with heavy wear or a rough history.

Is the 2021 BMW M3 safe?

The 2021 BMW M3 has not been crash tested by either NHTSA or IIHS.

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

BMW equips the M3 with forward-collision warning, automatic emergency braking, lane-departure warning, lane-keeping assistance, blind-spot warning, rear cross-traffic warning, drowsy driver monitoring, a post-crash braking system, and BMW Assist eCall with an SOS button and automatic collision notification. The Driving Assistance Professional Package adds adaptive cruise control with stop-and-go, extended traffic jam assistance, lane-centering assistance, evasive steering assistance, and emergency stop assistance, but it is available only on the Competition model.

The lane-departure warning vibration and lane-keeping assistance are called out positively in the test-drive notes, which is reassuring for everyday use. Still, the lack of crash-test results means you should lean more heavily on the available driver aids and the vehicle’s overall condition when shopping used.

Should I buy a 2021 BMW M3 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:

• 29.9% of listings are priced as good or great deals.
• Accident-free inventory is solid at 76.1% — always verify the vehicle history report.
• Price trend: Prices have held steady compared with last year.
• The redesigned M3 is described as a car that can feel like “multiple cars in one,” with especially strong performance in Competition form.

The bottom line: If you want the sharpest driver-focused version of the M3 and you value the manual-transmission option, the 2021 is the right target. If you are more price-sensitive, keep shopping the market closely and focus on the cleanest, best-maintained example you can find rather than chasing the newest badge alone.
