15. BMW M5 E39
Most people consider the BMW M5 they offered from 1998 to 2003 one of the best-performance sedans of all time. It is the best M5 model and a prime example of a German muscle car. You are probably asking what this model did to receive such high praise from car fans and motoring press. The BMW M Power department transformed the E39 5-series into a fantastic driver’s machine with numerous upgrades.
The heart of the car was a glorious S62 4.9-liter V8 engine with 400 HP. It sent all of its power to the rear wheels through a six-speed manual, which was the only transmission choice. The result was the ultimate driver’s sedan and an instant classic. It could jump from 0 to 60 mph in 4.8 seconds and top 155 mph, even when they electronically limited it. Today, the E39 M5 is still obtainable. Decent examples cost around $18,000, but you should hurry since the prices will probably go stratospheric soon.
