Used 2021 BMW M5 for Sale nearPhoenix, AZ

Is the 2021 BMW M5 a good car?

The 2021 BMW M5 stands out as a high-performance luxury sedan that blends serious speed with everyday usability. It was refreshed for this model year with a new iDrive infotainment system, a 12.3-inch touchscreen, and wireless Apple CarPlay and Android Auto, while the Competition model also got suspension changes aimed at improving ride quality without giving up its performance focus.

What makes it especially appealing is the combination of a twin-turbo 4.4-liter V8, an eight-speed automatic transmission, and xDrive all-wheel drive, plus the ability to feel more rear-wheel-drive when stability control is turned off. It also brings 600 hp, 553 lb-ft of torque, and a 0-to-60 mph time of about 3.3 seconds, so you get supercar-level pace in a sedan that can still handle bad weather.

For you, that means the M5 makes the most sense if you want speed, modern tech, and all-weather capability in one package. 31.4% of listings are priced as good or great deals, which gives you some room to shop selectively.

Is the 2021 BMW M5 reliable?

The 2021 BMW M5 is described as relatively new with no major reported problem areas or concerns. It also benefits from the sixth generation’s strong performance credentials and a refreshed cabin, which helps it feel modern and well sorted for its age.

There are tradeoffs, though: the sixth-generation M5 introduced electric steering, which did not please everyone, and the car’s high-performance nature means it still rewards careful ownership. For used buyers, the long-term risk is less about a known widespread flaw and more about the cost and condition sensitivity that come with a performance sedan.

What should I look for when buying a used 2021 BMW M5?

Accident-free inventory is solid at 75.6% — always verify the vehicle history report.

You should prioritize a history report, a thorough pre-purchase inspection, and close attention to signs of hard use or poor maintenance. Because this is a high-performance sedan, condition matters more than mileage alone, so focus on service records, tire and brake wear, and whether the car has been modified or abused.

Should I buy a 2021 BMW M5 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:

• 31.4% of listings are priced as good or great deals.
• Accident-free inventory is solid at 75.6% — always verify the vehicle history report.

Consider the 2022 if:

• It adds the M5 CS with carbon-fiber track-focused performance.

If you’re price-sensitive and want to maximize value, the 2021 is the smarter year to target; if you want the most extreme factory performance in the lineup, the 2022 is the one to compare against.
