So,
Bored with Audi, what may have you learned from the thread you started? Not quite a full Bavarian sausage, as it appears to have gone way off topic and I am as guilty as the rest.
My advice:
Diesel it must be. Go for the 330d M Sport xDrive Saloon or Touring, and load it to the hilt. Don't forget the Individual Leather. It's wonderful.
However, if you are willing to wait, possibly 3-6 months, and shell out even more money (looks like an extra £4000, so the Law of Diminishing Returns kicks in) for the 335d version, then do so.
