 I bought my 04 Touareg with 49,900 miles on it. Good thing I got the extended warranty because at 55K miles, the vehicle completely died in the middle of the road. Turned out to be the liquid cooled alternator. Not kidding, a liquid cooled alternator. That repair was over $1,000 but was covered under the extended warranty. The tire pressure sensors constantly act up and remind you about it every time you start the vehicle. Each tire sensor costs $700 to replace. The headlights were flickering on and off. I had them replaced at a price of $598 for the set! Most places wont change the oil, so dealership it was for me. $$$  To sum it all up, this car costs more to maintain than it's worth.
