So...........I'm a car guy.............and.............also bicycle guy, but what the heck does a 57 Chevy have to do with any Schwinn? It's not even the correct Violet Schwinn color. IMO, that's just the current owner Pacific Cycle exploiting the old Schwinn Brand. Milking $$$$$.
The only bicycle dealership I ever remember visiting having a shop vehicle painted was Doug Watson's GREEN'S CYCLERY in Fresno, CA. He had a '29 Ford panel delivery painted green (naturally) and was letter in gold leaf with the store name.
