I like your e38 man. You have to get that alpina front lip, it would finish everything off perfectly. Your x5 does not need those LED tail lights. Dont cheapen out your car by modding unnessary parts. I think the only thing that I think can make the 4.8is better is the addition of the under carriage bar. It makes it look so much more rugged and sporty. Anyways congratulations on your car and good luck with it.
