Hi,
My car (2006 A3) is up for 55k service and I called a few Audi dealers around my area. The min quote I was given is $650(if there are no problems) which i think is a rip off... I am trying to find a non-dealer audi repair shop in westchester. Do you guys have any recommendations?

Also my car is a CPO (certified pre owned), do you know if the warranty of the car would be void if I don't take it to the dealer for the 55k service. All replies are appreciated.

Thanks.
