It always depends on your service adviser and the dealership. A good Audi dealer will always supply better warranty service than a bad BMW dealer, and vice versa. I got crap service from Stevens Creek BMW in CA and awesome service from Daniels BMW in PA. My best service came from Carousel Audi in Minneapolis, MN. You have to ask around in your local area to see which dealer is rated better.
It's not a function of the warranty contracts between brands; it's the dealers.
Dinan compliment of stuff plus PF rotors and RG63s. Enough for now.
Why, yes. I am an abrasive bastard.
