Audi owners know how hard it can be to find someone besides the dealer who really know how to work on these cars. I had several coolant leaks that had been going on for months if not years (my stupid mistake to let them get so bad). Brought the car to GCD and they did an excellent job of repairing them all. The price was a few hundred higher than I expected, but so far the car runs very well with no problems. I was satisfied by the shops professionalism.
