I don't trust hardly any shop with my 2005 S4 Audi Avant, but Griffin is one I do. i'm surprised by the number of low ratings here, but I know cars are very complicated machines. What often seems causal is simply random failure. Just because you had the car in the shop last week, doesn't give it some protective force field to prevent all other failures. That would be nice, but there is no car karma. In fact, fixing one problem could lead to another... If you add new wider rims and tires, you are putting more stress on the suspension and steering parts, not to mention you will be breaking harder, since you now want to drive faster... So plan on some new control arms, thicker sway bars and larger break calipers and rotors. In trouble shooting car problems, it often takes a bit of hit or miss. It's not always as black and white as many would like. You have a slipping belt. Maybe it's old, the tensioner, or maybe your engine is throwing oil and it's going to be a much bigger problem. Knowing your car and it's normal noise/sounds is a good way to help and work with the technicians at Griffin. I've been to them for a couple of strange noises and we were able to identify and replace the parts rather quickly. By fixing the small problems before they became big problems, I probably saved a bunch $$$. The fuel filter/pressure regulator was causing the pump to make a strange noise. It's much cheaper to replace the filter than a pump or injectors... If you are looking for a shop that is passionate about their work, you've found it. They have strong opinions about cars, parts and politics. If you are timid and looking for a soft-touch, PC, salesperson, you might be better off at the dealer. Hanging out in the shop or show room is definitely not PG-rated, so leave your kids at home. Terry and his crew are not racist, but realists. They grew up in Berkeley and know what tolerance is. They also understand the cliques that exist around certain car brands and models. A car is often the extension of a person's personality and identity, and that's the way they treat it.
