Used 2020 BMW M5 for Sale nearBoston, MA

Is the 2020 BMW M5 a good car?

The 2020 BMW M5 is a high-performance luxury sedan that blends serious speed with everyday usability. It pairs BMW’s twin-turbo 4.4-liter V8 with an eight-speed automatic transmission and xDrive all-wheel drive, and BMW tuned that system for a rear-wheel power bias so the car can still feel playful when you want it to. For shoppers who want supercar-level performance, modern technology, and all-weather capability in one sedan, that combination makes it a distinctive choice.

It also got a couple of useful updates for 2020, including digital instrumentation and standard wireless smartphone charging. The tradeoff is that it is expensive to buy, maintain, and repair, so it fits best if you want the performance and are prepared for the ownership costs.

With 31.1% of listings priced as good or great deals, you have some room to shop selectively.

Is the 2020 BMW M5 reliable?

The 2020 BMW M5 is described as relatively new, with no major reported problem areas or concerns. That makes it a more reassuring pick than many older high-performance sedans, especially if you want strong performance without stepping into a model with a long list of known trouble spots.

Even so, it is still a high-performance car with expensive hardware, so careful ownership matters. For used buyers, the long-term risk is less about a known design flaw and more about the cost and consequences of neglected, abused, or modified examples.

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

At 69.7% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a full vehicle history report and then prioritize a pre-purchase inspection from a shop that knows high-performance BMWs. Focus on overall condition, signs of hard use, and whether the car appears to have been modified or poorly maintained, since those examples are the ones you want to avoid most.
