Are you looking to wrap your entire car, or just the trim / roof, etc? I'd love to get my roof in a matte or glossy black, but I suck at these types of DIY.
BTW, if you don't have it already, I have a roll of of 3M white matte and a roll of white glossy vinyl I got from 3M (54in by 5yd). Not sure if that's enough, but its just laying around at home.
