it is a well know fact that E39 (97- 02) is among the best BMWs. For its size, it has matchless handling. few cars of this era has heated steering. All controls inside are intuitive. Exterior is matchless and even now it does not look dated, in fact is still a head turner. You hear the bump but you dont feel it, suspension is so good. Compared to its competitors, E class or Lexus GS, it's sportier and should be the choice of a car enthusiast.
Handling, heated steering, suspension and shocks, the way it handles corners, looks.
