During a roadtrip, we were involved in a relatively minor car accident but weren’t sure if it was safe to make the 500-mile drive back home.

What a shop. We're new-ish to the valley and had been on the hunt for a good, honest mechanic and we've no doubt found it with Casey and his crew at Ace Auto. My wife's car had a rear diff leak and I thought for sure it was a bad seal or worse. Come to find, the fill plug had worked it's way loose and it was weeping from there. While he had the car, I had him look at the brakes because I knew we were getting close to needing pads and rotors. Casey let me know that only the front really needed attention, but I had him to all four anyway. With so many opportunities to upcharge me for unnecessary work, they were dead honest and phenomenal to work with. Prices are very fair and the work quality and customer service is exceptional. The shop isn't too close to us, but we'll be making the drive to come to Ace because it's absolutely worth it.

During a roadtrip, we were involved in a relatively minor car accident but weren’t sure if it was safe to make the 500-mile drive back home. We thought it would be best to have someone take a look at the car first, and we’re grateful we did. Casey took the time to carefully inspect the vehicle and reassured us that the damage was only cosmetic. He was willing to fit us in even though it was getting close to closing, and he couldn’t have been more kind and understanding. We were able to eventually drive home safely and get the car repaired closer to home. We’re very grateful for his help and truly appreciate his expertise and service!

Ace’s was recommended to me by two of my closest friends. Normally, getting work done on my vehicle feels like a chore because I hadn’t felt as if I found a legitimate mechanic. I took my overheating 1999 Subaru Forester to Casey on a whim, & immediately felt that he was fair & wasn’t gonna haggle me. I dropped my car off at about 4:30 & it was ready to be picked up the following morning! Highly recommend this shop! They work with integrity & a sense of urgency!
