I need to replace my S3. Can't quite afford S4 but have seen a A4 Avant Sline quattro 190bhp with a few extras. looks the part but dissapointed by the performance - felt a bit boring! should I wait till S4 prices drop or live with the S line? Are all 04 SLines 190bhp and are they rare? Any other suggetions for an S3 replacement with 5 doors?
