I'm torn on the newer VWs. I'm a VW nut, but around 97 or 98, their QC started dropping. I heard about them having a LOT more problems than they used to. It could be a great car, it could be a money pit. You have to keep the oil changed regularly, but you NEED to use the oil recommended by VW on these cars. Usualy, I don't use the "recommended" oil, but I've seen many problems caused by using the wrong oil on them. It's a specific synth, and it's a little more expensive than most. If you don't, the IP can go bad, the turbo can coke up, amongst other problems. Get the full service history of the car. Take it to a trusted mechanic and get it looked over, somebody who knows these cars. Get on vwvortex.com and see what folks there think. The jury still seems to be out about the viability of biodiesel in these cars.
If you really want it, be careful. Don't jump on this one thinking it's cheap. There may be a good reason!
