So I went to an autocross event in my friends M3, and now I want to get a RWD second vehicle that can be my summer/autox car. Thing is it needs to have a somewhat functional rear seat for my (1 year old son) ,of course has to have a standard transmission, and be available for under $10,000. The only things I keep thinking of so far that fits the bill are BMW’s and older M3’s. looking for some guidance/opinions from TLC. Thanks!
