7: BMW E39 M5
The E39 M5 was a winning combination of style and substance as another reveled chapter in the long heritage of the M5. The styling was iconic with early 2000s BMW and proved ubiquitous overall. Performance was also top-notch, with power coming from an optional V8 engine (via Road & Track).
There are few sedans in this size and segment that can match the performance of the E39 M5. The E39 has proved to be an icon in the BMW community time and time again. From the timeless design to the standard amount of luxury features, this car is still an excellent driving vehicle today.
