Is the 2020 BMW M5 a good car?

The 2020 BMW M5 stands out as a high-performance luxury sedan that blends serious speed with everyday usability. It uses BMW’s twin-turbo 4.4-liter V8, an eight-speed automatic transmission, and xDrive all-wheel drive, so you get the kind of traction and pace that make it feel far more focused than a typical executive sedan.

For 2020, it also gained digital instrumentation and standard wireless smartphone charging, which modernized the cabin without changing the car’s core mission. The performance numbers are a major part of the appeal: 600 hp, 553 lb-ft of torque, and about 3.3 seconds to 60 mph, with a 190 mph top speed when equipped appropriately.

If you want a sedan that combines brutal acceleration, modern tech, and usable all-weather capability, this is a strong fit. Market availability is also reasonably supportive, with 27.8% of listings marked as good or great deals.

Is the 2020 BMW M5 reliable?

The 2020 BMW M5 is described as relatively new, with no major reported problem areas or concerns. It also keeps the sixth-generation formula that pairs serious performance with everyday usability, which is part of its appeal if you want a fast sedan that still works as a daily driver.

That said, high-performance ownership still calls for careful maintenance and a clean history. For used buyers, the long-term risk is less about a known widespread defect and more about the cost and consequences of neglected service, hard use, or poor prior ownership.

What should I look for when buying a used 2020 BMW M5?

Accident-free inventory is solid at 77.8% — always verify the vehicle history report.

You should prioritize a history report first, then inspect the car closely for signs of neglect, abuse, or inconsistent maintenance. Because this is a high-performance sedan, condition matters as much as mileage, so focus on service records, signs of modification, and whether the car has been cared for like a performance vehicle rather than just a luxury commuter.

Is now a good time to buy a used 2020 BMW M5?

• Deal availability: 27.8% of listings are priced as good or great deals.
• Inventory: There are 126 listings available.

The bottom line:

The 2020 BMW M5 makes the most sense if you want the core M5 formula with strong performance, modernized cabin tech, and usable all-weather capability. If your priority is finding the best value, you may want to compare nearby years and focus on the cleanest, best-priced example rather than chasing a specific model year alone.
