Despite what my name says, I know more about BMW's than any other cars, period.
Here's the lowdown:
E30 M3, S14 Engine, 200bhp, 5 Speed Manual.
E36 M3, S52 Engine, 286bhp, 321bhp for EVO, 5 Speed Manual, 5 Speed Automatic, SMG I, and 6 Speed Manual on the M3 EVO.
E46 M3, S54 Engine, 343bhp, 6 Speed Manual, SMG II(with auto and different levels of clutchless manual, depending on how aggressive your driving style is)
If you live in NA, figures are as follows:
E30 M3, 192bhp, 5 Speed Manual
E36 M3, 240bhp, 5 Speed Manual or 5 Speed Automatic
E46 M3, 333bhp, 6 Speed Manual, SMG II(with auto and different levels of clutchless manual, depending on how aggressive your driving style is)
Well, there you go. If you truly need an Auto, you have to go with the E36, but it is a great car, my dad has one.
Bro found an E30...
Now I begin my two year search of the perfect car for me.
