Hi guys, I am new to the forum, and am looking to buy a bmw 3 series. Besides the M3, which is the best or one of the better 3 series models in terms of suspension, power, and modifcation possibilities? I would use it as a street car, but also autocross it about every month. Hope you guys can help me out with some suggestions (model, year, options, etc.) on which model to buy. Thanks, paul.
