Used 2021 BMW M5 for Sale nearPhiladelphia, PA

Is the 2021 BMW M5 a good car?

The 2021 BMW M5 is a compelling choice if you want a high-performance luxury sedan that still works as an everyday car. The overview describes it as blending serious speed with everyday usability, and it adds a refreshed look plus a new iDrive system with a 12.3-inch touchscreen and wireless Apple CarPlay and Android Auto.

It also brings a twin-turbo 4.4-liter V8, an eight-speed automatic transmission, and xDrive all-wheel drive, while still allowing a rear-wheel-drive feel when stability control is turned off. That makes it especially appealing if you want fast all-weather capability without giving up a modern cabin.

There are tradeoffs, including electric steering that may not suit every enthusiast and the need for careful ownership given its performance focus. Still, the model is described as relatively new with no major reported problem areas or concerns, and 27.4% of listings are priced as good or great deals, which gives you some room to shop selectively.
