Does the S3 have four wheel drive as standard or is it an option? I used to have a Seat Leon Cupra for a while, a nice car but it seemed to suffer from wheel spin and understeer quite a lot.
I think the S3, A3 1.8T, one of the high end Golfs, a Skoda, and the Seat Cupra all share a lot of parts (all built by VAG).
