Been pretty happy at Alpine but have had a few misdiagnosis incidents but overall ok. I sometimes wonder what else to compare to??

The shops that I know that are good (from reputation not experience) are:
Streamline in Sugarhouse
TDC (roughly 33rd S and 3rd W)

Tas Tire up in Ogden (17th S and Washington) ... run by Brent Savage who drives a 90 Quattro ... good shop that I've had a bit of work done there.

No idea about stuff down in the Provo/Orem area.
