For a longtime I've been looking for an A4 Quattro in the B5 shape, but very rare here, and there are only 3 x S4's in the entire country. So I'm now considering buying an S3 from around 1998 to 2000, of which there are quite a few. As I know virtually nothing of the S3 spec can anyone advise me on what models were made, engine sizes & are they all quattro? I want power on all wheels, very fast and what upgrades. Is there a supercharger available like the PES for the A4?
