The BMW E30 is quickly becoming a cult classic among the DIY, autocross, and track crowd. And though the M3 version may be climbing so quickly in price, soon no one will be able to afford one, the 325i, as it turns out, has some chops as a great platform for tuning. Kameron Baker's homebuilt E30 is just about the nicest one we've seen, and if you think it looks great, wait till you see how it drives.
