Like coxw says, whilst the S3 is not a big enough leap, there is nothing really out there that justifies the change to bring even more performance. Whilst 4WD would be nice or with a diff, our current driving cannot justify buying a 4WD car when a FWD car will do the job for all our driving requirements. I understand that for some folks, the 4WD is required for the local roads so here I cannot make any comment. The Costs to make the change can be equiv to a small 2nd hand econohatch. Our family is considering keeping the car and going in for a Fiat 500 abarth or Punto esse esse instead for a small engine runaround town. Whilst the Punto is 17K the 500 is 13k, and that can be negotiated a little
lower. The hit on the car is already between 7-10k so the 3k odd difference and we then get another new car. 2nd hand would make the differential even less. Choose another small 2nd hand car and the costs are
lower still. Small local trips can be done in the small car and the longer trips or trips where we need to carry lots is done in the
cupra. For the money we would lose in changing the car for something with equiv or more performance we can get 2 cars, which suits us both right down to the ground at the moment.
However, having said that, I do like the thought of an Audi RS4 / RS6. But for us that is only a 6 number dream
