We love Good Works. We've been taking our cars there for a few years now and have had nothing but good experiences. They always do a good job and are reasonably priced.
I don't know a ton about cars, so I'll keep this short, but I can say this... They've impressed my husband, which is not easy to do! I love him, but my Mike can be a pain in the butt and asks a million questions and Glenn and the people at Good Works have managed to impress him thus far ;)
The only "meh" thing about GW is it's hard to find your first time going there and you have to all but come to a complete stop in the road to go into their parking lot because the entrance is banked so frigging steep. Obviously, this has nothing to do with them or their service, though. Just be forewarned or you'll need more work done on your car haha
