The reason I went for the Sport spec is, other than being £1k cheaper, the Audi garage had a fully loaded demo car for the taking with no miles on the clock. I have to wait until 17th April for collection though. Can't wait.
Your right M_D_O_London very rare car. Only seen two S-Line quattro's in Portsmouth area. No Sport specs.
Its a shame you don't see many TFSIs compared to the diesels. Unless you are doing over 16k miles per year I don't think the diesels are any cheaper to run in the long haul.
