Firstly hi to everyone. My question. I'd like an A3 2.0 tdi and i usually buy from the main dealer. I'd also like 17 inch alloys and leather. The problem is finding one at the right price. One option is to buy a standard 2.0 tdi, then look for some alloys and leather secondhand. How simple would that be to do. Is the leather interior on an A3 just a change of seats, or is it the door cards as well. Is it a straightforward swap, or would you hold out for the right model. Thoughts please.
