The e30 M3 was built for the track and won many races.
The e36 M3 was built for the track as well as the road and featured staggered wheel sizes and an I6 that produced around 320HP from a 3.0 or 3.2 liter engine depending on when the car was manufatcutred. In mid-late 90s there was a 4 door version.
The current M3 (e46) produces 333Bhp from a 3.2 liter inline 6. and has nearly all the ammentys one could want as options from heated seats to stabilty and traction control.
The ultimate "Whip" for any 16-21 year old male due to its ostentatiously good looks and striking road presence (unfortunately none of them can afford one).
Nate: cool story brah I can't wait to blow past your trash talking ass in my stock bmw m3 with 444 horse power at 180mph ripping through your ass like an f22 raptor. Better hold onto your shit tight.
