 Verified Service was terrible! Left key in car, windows down, unlocked for hours. Never called to say it was finished. Told that part was replaced that morning, asked if it mattered, they said no, then failed the SMOG for that EXACT REASON and made us pay. Will never go back!!

 Verified I came in on Monday around 11 am.  No appointments are needed.  They share a building and parking lot with a mechanic shop, but they still had parking spaces available.  

The young lady in the front (I am sorry I did not get your name) is incredibly efficient, professional and friendly.

They were working on a truck when I arrived, but I was still done and on my way in about 10 minutes.  

This was the most professional, clean, efficient and friendly smog shop I have ever been to.  

Thank you so much!

 Verified Took my 2009 Silverado to All Pro Smog in Manteca and had a great experience. They got me in and out quickly and were very professional and friendly. Sim, the technician, was awesome and fun to talk to, and the lady at the front desk was very sweet. I'll definitely be back for future smogs. Highly recommend!
