Hi I'm looking to buy a 2001/2002 A4 Avant 2.5TDI 180 Quattro and could do with some guidance about what to look out for and some suggestions as to what I should be paying for this. (I've not had an Audi before) 1) Anything serious to look out for? 2) Is there a limit to mileage that I shouldn't consider going over? 3) I believe the cam belt needs to be changed every 60K miles - is this correct? 4) What is the difference between the SE and the Sport editions? 5) What should I expect to pay for a sport or SE 2001/2 with <70,000 miles? Your help would be greatly appreciated!
