This was the only place that can get my tire on the fly. I have a tire size that's hard to find quickly and The pricing was perfect. The service was great!! And pretty quick. I came in today and will be back in a few weeks for more work. I had a screw that was in a very bad area of my tire preventing it to be repaired. Before they charged me for the tire they took a look to see if it was repairable. Thanks guys!! Darcie Ragans

These guys are awesome Francisco has the best customer service he's staying after closing to solve a problem with my dad's ac. The cost isn't worth staying after but he goes above and beyond. This is my new place to bring my truck and refer my friends and family to, not only is it low priced service they are also honest. Good luck FNP wish you guys the best keep that 5 star rating you guys are number 1!

Went back to ATD saw alex and Tony, They got me in and out for another full synthetic oil change. Took care of my car and got me back on my way. Love this place. These guys the staff and the mechanic on duty are awesome. Aaron Doolittle

Very bad service. They don't honor a verbal promise.Calif Labor Code:920. The employee refused to give me a free retest.Even though he had evidence I was a customer entitled to a re-test.Breach of Contract. His words were as follows:"Get out of here ,I don't want you're buisness." I was definetly mislead in comming here.

Came here because I had a flat tire. But not only that I needed an oil change so this individual camilo took care of me really fast. Not only was he fast he had the best customer service I have seen in a while. I highly recommend checking this place out. Great job u guys. Ask for camilo hes the best! Jonathan Cook

Had two flat tires on the way to get a horse. These guys changed what was wrong in literally 5 minutes no muss no fuss! Amazing place will be back to get our tires done in the future! Jamie Schicht
