Used 2021 BMW M3 for Sale nearSacramento, CA

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 115 listings available, which suggests a fairly limited pool of used M3s to shop from.

Is the 2021 BMW M3 a good car?

The 2021 BMW M3 is a strong fit if you want a luxury performance sedan that can be both usable and genuinely exciting, and its 3.67/5 user rating and 6.67/10 expert rating reflect that split personality. The standout strength is Performance at 10/10.

It delivers the kind of driving experience that makes it feel like “multiple cars in one,” with a powerful engine, a manual transmission available, and sharp responses that make it especially appealing if you value engagement over comfort. The trade-offs are real, though: poor ride quality and not much cargo space mean you give up some everyday polish for the sake of speed and driver involvement.

With 30.4% of listings marked as good or great deals, you have some room to shop selectively if you want the right mix of price and equipment.

Is the 2021 BMW M3 reliable?

The 2021 BMW M3 is built around a high-output performance formula, so you should expect a car that rewards careful ownership and regular maintenance more than a low-stress commuter. The expert notes emphasize that it is engineered for serious driving, with cooling systems designed around engine, oil, turbocharger, and brake demands.

The performance notes also point to a car that can be driven smoothly and precisely, but one that can feel like it may bite if you make sudden inputs. That matters for long-term ownership because a used M3 is more likely to have been driven hard than a typical sedan, so condition and maintenance history should matter as much as mileage.

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

Accident-free inventory is solid at 76.5% — always verify the vehicle history report.

You should start with the history report, then prioritize a thorough inspection of the suspension, brakes, tires, and interior wear, since this is a performance sedan that may have seen spirited use. Pay close attention to how the car presents overall, because condition can tell you a lot about whether the previous owner treated it like a daily driver or a track-capable toy.

Key things to evaluate:

• Trim level: The base car emphasizes the manual-transmission driving experience and the core performance hardware, while the Competition model adds more power and an automatic transmission. If you want the most engaging setup, the manual-equipped version is the one to focus on; if you want the quickest and easiest-to-live-with version, the Competition model is the better fit.
• Powertrain: The standard setup 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 base car uses a six-speed manual, and the Competition uses an eight-speed automatic.
• Safety package: Standard driver aids include 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. The Driving Assistance Professional Package is only available 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 are a standout.
• Fuel efficiency: The test-drive notes say fuel economy drops 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 choose if you want the manual transmission and the purest driver involvement. It gives you the core M3 experience with the twin-turbo inline-six, rear-wheel drive, and the six-speed manual, making it the best fit for enthusiasts who value engagement over convenience.
• M3 Competition: This is the better-value choice if you want the quickest version and prefer an automatic. It adds more power, quicker acceleration, and the eight-speed automatic, and the expert notes make clear that if you do not want to work a clutch, this is the easier recommendation.

The Driving Assistance Professional Package is only available on the Competition model, so that trim also gives you access to the most advanced driver-assistance upgrade.

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

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

• Deal availability: 30.4% of listings are priced as good or great deals.
• Inventory: There are 115 listings available.
• Price trend: Prices have held steady compared with last year.
• Clean inventory: 76.5% 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 $69,944 sits slightly below last year's $70,282.

That small decline suggests the market has been fairly stable rather than volatile. For a future seller, that usually means you should expect value to move more with condition, mileage, and equipment than with broad market swings.

Because the price change is modest, a well-kept M3 with desirable options should remain easier to position than one with heavy wear or a rough history. If you plan to sell later, keeping the car clean, documented, and unmodified should help protect its appeal.

Is the 2021 BMW M3 safe?

The 2021 BMW M3 does not have published crash-test ratings from either NHTSA or IIHS, so you should lean more heavily on its standard driver-assistance equipment and the car’s overall condition when shopping used.

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, post-crash braking, and BMW Assist eCall with an SOS button and automatic collision notification. The Driving Assistance Professional Package is only available on the Competition model and adds adaptive cruise control with stop-and-go, extended traffic jam assistance, lane-centering assistance, evasive steering assistance, and emergency stop assistance.

One important caveat is that the most advanced safety package is tied to the Competition trim and automatic transmission, so base-trim shoppers do not get that upgrade path.

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:

• 30.4% of listings are priced as good or great deals.
• Accident-free inventory is solid at 76.5% — 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 calm when you want it to and ferocious when you do not, with especially strong appeal for buyers who want a genuinely engaging driver’s car.

The bottom line: If you want the most distinctive version of the M3’s modern performance formula, the 2021 model is a compelling place to start because it combines serious speed, everyday usability, and a stable price trend. If you are more price-sensitive, you can still shop the broader market carefully and focus on the best-maintained example rather than chasing the newest or most heavily optioned car.
