congrats on your purchase OP !
the Boss 302 does look great and seems to perform as well. forget all the haters here
and for those saying "wait until a problem arises and your warranty wont be worth sh**", well, correct me if i am wrong, but it would be the same, if not worse with a M3, right? the only difference is that Ford parts are probably 20-30% less than OEM BMW parts... so even if you're getting fu**ed by the dealer, it wont be quite as painful...
Enjoy your ride !!!
