Hi, looking to buy an A6 Avant for the winter as planning a few trips to Scotland or the Alps. Ideally it's going to be the TDi Quattro as this should be much better in the snow particularly if I get some winter tyres fitted.

Does anyone on here own one of these?

Any particular problems to look out for when buying these cars?

Any info anyone can give would be a big help as because this will be a second car, than I can't afford to end up with a lemon.
