I hear people rave about GM GoodWrench all the time, so when my mini-van broke down, I decided to give them a try. I brought it in, they had it for a day, and then I picked it up and it still had the same problem. So I brought it back in, and they fixed it with a large discount (would've preferred free). Aside from that, the customer service was exceptional. And albeit I was a little angry about my van, I will probably go there again, as the failure to fix my van's problem was probably an odd isolated incident.
