Bought my CPO Audi from a private party out of state (back when the CPO could be transferred, unfortunately no longer an option with Audis) and have taken it for service at German Auto, Prestige, Community Auto, Rochester Audi, and Delta. By far my best experiences have been at Delta, and this is from someone who is wary of "stealerships." German Auto and Community are closer to where I live and work, but it's been worth the drive for me to take it to Delta. The repair costs are usually the same, sometimes a little higher than the independent shops, but in my experience, they almost always get the job done right the first time. (An aside: at Community, I was told I'd "have to get used to it" regarding a rattle after a $2000+ suspension upgrade, a problem that turned out to be a loose fastener. At German Auto, they charged me for a windshield wiper fluid top off (!!) following a $800+ timing belt change. It's the little things, guys! Prestige's hours suck.) Delta has provided me with free loaners when my car would be in longer, even now when the car is no longer under warranty. All in all they treat my car and me very well. The waiting room experience is pleasant, too, although last time I was there it was a bit crowded.
