After being relocated to the Denver area, I was in search for a good garage so the search began. Being an owner of a B6 S4, and driving into the area, I noticed a difference in driving the vehicle due to the elevation difference from sea level to mile high. I called them up after doing a web search for garages in the area and they were nice enough to tell me to stop right over. Just from talking to Brian and Phil over the phone, I got a good sense of security that any issues that popped up they would be open to taking on the challenge. So after meeting Brian and Phil in person and my concern with the engine performance, they pulled out the VAG-COM, ran the codes, checked everything out, and when I asked what I owe ya...they said don't sweat it and sent me on my way. Coming from the east coast and only being in the CO area for a day or so...I was confident that the decision to keep Avalon as my garage was locked up. I also jumped on some of the local audi forums and posted the question about Avalon and local garages, and hands down everyone posted Avalon was the key choice and Brian's always there to help. Being in the Denver area for 6 months now, and picking Brian & Phil's brain more then once, sometimes I'm sure they thought I was a pain in the a$$, I can say if anyone's looking for a honest helping hand and a shop that can do it all, Avalon is the place to go.
