Just for your info: There is an UK based company specialised in replica-kits for different cars. They have two very nice ones; Schnitser & Zender. Made of GRP including front, side & rear apron. Exactly like originals but at a fraction of price. They have no homepage but at fax# int 44-1226-700776 you can reach them. For how the Schnizer looks, look at http://users.50megs.com/bmwalpina/maingallery.html
Click tuners then Schnizer/older models. Note, that car is not lowered. It looks great when lowered, but not "overdone" as many otherkits do.
