in my family there is a '01, and an '03 TDI. i wouldnt say they are the greatest, the "01 is definatly more reliable than the '03 (by far!). they definatly get GREAT mileage, however around here they are going for way over book value due to the high demand. i would not want to pay a high price for one, just to have some other fuel efficient autos hit the market and drive the demand back down for the tdi, making it worthless. that is around here in CT, where everyone drives to boston, NYC, or springfield to work...so the demand may not be the same where you are....?
