2007 BMW 3 Series 335i 2dr Coupe (3.0L 6cyl Turbo 6M)
I love this car inside and out. The only flaws are that the shifter has a slightly long throw (but that can be easily replaced aftermarket), the seat belt pusher is flimsy and weak, and the iDrive is just kind of annoying, but nothing that isn't worth not getting the car. Vishnu's XEDE is also a very welcomed mod, opens up a lot of the car's true power.
The addicting acceleration.
Ditch iDrive for better system (I know I know, won't happen), build sturdier seat belt pushers.
