Figured this was the best place to post this, plus I didn't see a sub-forum for AZ.

I started a head gasket job on my E36 M3 (S52) a while ago, but I ended up moving before I could finish it and I no longer have access to a garage or a good place to work on it. I am hoping to drop it off at a shop and have them finish it up for me, but have yet to find one that I trust. I found a few that look good online but you can't always tell what you're getting from the internet - has anyone had any experiences with these shops or have one they'd recommend? Preferably in the Tucson/Phoenix area, but I'm willing to go farther for good work. Thanks guys!
