Myself and others here at spooledupaz have used the Foxglen auto spa @ Foxglen and Butler intersection (well just west on Butler from it).
As far as working on your whip well that's different a members garage is usualy a nice place, lifts are hard to come by unless you get hooked up with the right people.

Mitsured is a mech at Flag Honda and can help when he has the time (I'm sure he won't mind helping a fellow Mistsu driver). As for shops I've used Competition auto for body work. I do all my own repairs outside of the body work so I don't know about tune-up shops. Tuner shops there is MF Motorsports I think they are still open,if this is what you were looking for hit up Cardon there.
BTW if you want to meet alot of us you may come to the BBQ at my place in Sedona this Saturday. Check the forum thread for details, you may bring a guest with you if you like.
