I'm not sure what rock Elton "the reviewer" climbed out of, but he is probably one of the low grade mechanics down the street. I've been a customer of Griffin for over half a decade and his team is the only team I trust my classic 928 to handle. As to honesty, I've had Terry come in way under his original estimate a number of times as he found a part at a better price and passed the savings on to me. More than that, the one time I thought I had needed a serious repair he came back with a solution that saved me a 1/3 of the cost - and he didn't have to as I fully believed I needed the repair. I have also seen him back his work. When a new part failed soon after they put it in, Griffin not only replace the part but also did it at no additional cost. I said this on my original review and I will say it again - If you are the jiffy lube, gloss it over, do not really care about your car, let's do this as cheaply as I possibly can type, you are at the wrong shop - go to Costco. If you have a performance car or prefer to treat your car like it is one - go here. I would also be highly suspect of people claiming they went here and got "ripped off". There is at least one garage claiming to specialize in Porsche work trying to steal Griffin's customer base. I know - I've gotten their stupid flyers on my windshield at BART (which I *hate* btw). That competitor appears to over promise, over charge and under deliver. I have seen Griffin stand by their work. They build long term relationships with their customers and you don't get that by being any other way than honest, fair and good at what you do.
