No matter WHERE you find it, it'll be pricy as shit, because its so new, i don't think you'll even get much of a discount on a group buy, but consider me IN, if you do, NEXT,
www.strictlyforeign.com, i believe also has the bumber, and 2 different styles of it (i think one is the M5 front skirt) for the E36, there both around 6 bills american, but your best bet would be the MA SHAW one because, i'm pretty sure ALL of their products are made from CARBON FIBRE, which is ALWAYS A GOOD THING,
hope i was of some help, and get back to me if you guys get a group buy!!
