I had a friend refer me to this shop as I wasn't happy with the business I had used prior. I've had 3 different services done over the last 3 or 4 years on two different cars. Not knowing much more than basic auto care, I have to rely on what I'm told or I can research. The seller for me was that they found 2 issues with my vehicle and advised me that one of them would be much cheaper at a nearby audio store. I'd likely have paid whatever they quoted on it and they would profit more, but they did what was in my interest. Goes a long way in my book. Puts me at ease about the diagnostics they do and their solutions.
