that's a good suggestion..........
BUT, if you want to rock the OEM stuffage........either go to your good local parts store (not talking about Pep Boys here, a good aftermarket euro place) or run down the supplier of the covers to BMW (should be a tag somewhere on the seat) and give them a shout.......
Benz said i couldn't get covers for the old 75, but a quick call to the supplier said that they were still available
