21. BMW E39 M5
The M5 BMW built from 1998 to 2003 is widely considered one of the best performance sedans of all time. In fact, it was the best M5 model, as well as a prime example of a proper German muscle car. The BMW M Power department transformed the E39 5-series into a fantastic machine with numerous upgrades.
The heart of the car was a glorious S62 4.9-liter V8 engine with 400 HP. And it sent all its power to the rear wheels through the six-speed manual, which was the only transmission choice. The result was the ultimate driver’s sedan and an instant classic that could jump to 60 mph in 4.8 seconds. It had a top speed of 155 mph, even though they electronically limited it. Today, the E39 M5 is still an obtainable and affordable car.
