The year I had to wait after ordering this car was well worth it. After 4 years I still absolutely love my M3. This is the best car I've ever driven. I only hope BMW doesn't ruin the M3 when they finally update to match the new 3 series body style.
Handling, cornering, accelleration, absolute 100% solid control and responsiveness, and of course, the look.
The stiff suspension gives me all of my favorite features listed above, but it doesn't feel so good on the rough American roads. This car also doesn't announce itself well. It is too quiet, give me a louder exhaust!
