am i right in thinking all quattro auto will be tiptronic and not the poor perception/review of multitronic? any issues with these, do they have a cam chain? anything to take note on used examples at circa 80k on a 2005 plate? what do you think is a good price for a 2005, 3.0tdi avant with about 80k? i'm not really one to look at such high mileage cars due to more expense on maintenance and resale value of being such a high miler opinions?
