  • First off, these guys know their car stuff, but were still willing to listen carefully to what I (who doesn't know much car stuff!) had to say and what I wanted done. Since I had to wait a couple hours for the repairs, they set me up in the very nice waiting room with wi-fi so I could connect to my work while they did their work. And in the end, I got my car back with everything working, a great explanation for what they did, and a reasonable price. BTW, their website is easy to use, as well!

  • ASG correctly identified a no-start issue on my Mazda after another shop tried 3 different fixes. They were also invaluable in their pre-purchase inspection, steering me away from a car that looked good on the outside but turned out to need to much work on the inside. Their pre-purchase inspection of a rather unlikely find found a diamond in the rough! Their thorough inspection gave me a clear idea of repairs needed over the next few years and I felt very confident in my purchase negotiations.
