I bought the 1999 Passat Wagon used in 2001 or so, with 24K miles on it. It had been an executive car at VW in Dearborn. It must have been charmed, because it was the lowest-maintenance car I've ever owned. I hardly had to spend a dime on that thing except for oil changes and some regular, reasonable maintenance. This was before VW decided to make everything so difficult to repair on all their cars, so the dealers could make a fortune off of consumers with silly repairs. I was able to do simple things like headlamp replacements myself. In 2004 I stupidly traded it for a new one at 0% financing and now I'm stuck with a lemon. Don't buy an '04 Passat Wagon!
Comfort, ride, reliability, mileage, efficiency, lack of breakdowns, low-maintenance.
