I have 73,000 miles on the car and have had no maintenance needed other than the standard periodic checkups and oil changes. I have better than 50 mpg'total (I have not added it up since 50K but at that time it averaged 50.83). I have own 5 V.W. diesels and put on nearly 150K on three at 10, 12 and 17 years old. I would stay away from the gas version of the cars but I intend to keep this one and would purchase a diesel again.
