Used 2021 BMW M5 for Sale nearHonolulu, HI

Is the 2021 BMW M5 a good car?

The 2021 BMW M5 is a strong choice if you want a high-performance luxury sedan that still works well for everyday driving. It pairs BMW’s twin-turbo 4.4-liter V8, an eight-speed automatic transmission, and xDrive all-wheel drive with a rear-wheel power bias, so you get serious acceleration without giving up all-weather usability. BMW also refreshed the styling for 2021 and added a new iDrive system with a 12.3-inch touchscreen, wireless Apple CarPlay, and wireless Android Auto, which makes the cabin feel more modern and easier to live with.

For shoppers who want a performance sedan that can handle commuting, road trips, and bad weather, the M5’s blend of speed and practicality is the main draw. The tradeoff is that it is expensive to buy, maintain, and repair, and it is not a subtle car.

31.9% 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 best understood as a high-performance luxury sedan that delivers serious capability and everyday usability. Its xDrive all-wheel drive, eight-speed automatic transmission, and refreshed tech package make it a compelling option if you want speed and comfort in one car.

That said, it is still a complex performance sedan, so long-term ownership risk is higher than what you would expect from a mainstream used car.

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

At 73.4% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should run a vehicle history report on every candidate and prioritize cars with clean records and consistent maintenance documentation. A pre-purchase inspection should focus on signs of prior bodywork, uneven panel gaps, tire wear, brake condition, and any evidence that the car has been driven hard or neglected. Because this is a high-performance luxury sedan, condition matters as much as mileage.

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:

• 31.9% of listings are priced as good or great deals.
• At 73.4% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

Consider the 2022 if:

• It adds the M5 CS, a more extreme, track-focused version with a sharper performance emphasis.

The bottom line: The 2021 BMW M5 is the better pick if you want the sweet spot of modern tech, everyday usability, and serious performance without chasing the most extreme version. If you are price-sensitive, the 2021 also gives you a chance to shop a broader used inventory and compare condition carefully before paying for an M5. If you want the most hardcore interpretation of the nameplate, the 2022 is the year to look at instead.
