After everyone's "connection" to a mechanic failed me, I turned to my trusty friend Yelp. My car's check engine light was on and needed to pass emissions. Tempe Auto was fast, professional, and honest. I had taken the car to another shop and they said it would take a few days to fix- these guys had it done in a few hours. They said they work with lots of students/ out of state parents. (Luckily my dad was in town at the time...and I'm not even a student anymore. I am, however, a spoiled brat.)
I recommended the shop to a friend who had a mystery issue with his car. They ran diagnostics/checked it out and didn't find anything wrong. They didn't charge him anything.
Check em out!
