This is the most legal fun you can have! The only complaint I have is about the HORRIBLE Harman-Kardon speakers... I have heard better in a VW Beetle. There is no excuse for BMW to use this poor quality. It is one of those things you understand that you will just HAVE to replace.
The sound of that motor! Also, corners like a champ!
Improve seat comfort and please... those Harmon-Kardon speakers couldn't be worse.
