I'm going to begin autocross racing in 2005, and I want to do it in a BMW. Since I'm 18 and can't afford an E36 to beat around, I'm looking to purchase an E30. The only problem is I'm not sure what one I want. Do I want a high reving high HP 325is or should I get a low reving but torky 325es. Could anyone also tell me what stock SCCA class these cars would be in?
