: I have been really thinking in my head if I should stop working on upgrading my 328 cause why waste the money if I'm going to get a M3 right? But should I do that or just keep my 328ci for the rest of the 3 years and trade out then? Any opionions???? : If I keep my car then I already have everything set to do the Dinan CAT System and Stage II Program for $1000 otd and the Remus DMT Exhaust for $520 otd.... : my bmw page: http://www.mp3ecstasy.com link to BMW
