Wolf's is the absolute best!!! I have a 2001 Audi that he has kept alive and running well for me for years now. I will not go anywhere else (even though I live in Henderson and his shop is a bit of a drive). I highly recommend him to all VW and Audi owners. He is honest and fair. And he lets you know what to expect to have to fix based upon your mileage, so you can budget.
(Incidentally, to those who wrote differently, and assumed what I had as well: the German lady who works for Wolf is not his wife)
