These are known as 'Largo' alloys and were a 17" VW upgrade option on the B5 and B5.5 Passat. I ran a set on both my 1.8T Passat saloon and my 1.8T Passat estate. Very nice wheels that were lighter than the 16" Sport and made both vehicles ride better despite the lower profile tyres (225/45 17). Not that common either!
