Leave the Audi Allroad alone, slow as all get out.
The Audi A4 with the 3.0TDi is a fking cracker, I was very impressed with it.
My wife has a Jetta 2.0TDi, goes great and is excellent on fuel. The missus loves it.
The Audi will be worth more when you come to trade it.
Do not do anything with the Citrus, fkn shit heap.
Forrester TDi or an Outback?? Get a lot of car for the money.
