You will always find excellent, honest, and professional service here. I've used Honest 1 Auto for about 4 years now and they guarantee their work. Among the many various services over those years, I have had oil changes, brake fluid exchange, transmission fluid exchange, starter replacement, strut replacement, etc. I trust their work and will continue to use them even though I have moved farther away now, I will drive back to this shop. It's hard to find another auto shop as trustworthy and reliable as them.

Check engine light was flashing and our over 250,000 mile 2003 GMC Envoy was shaking and running rough. Thinking we were going to need a replacement car soon we still got it to Honest 1. Got a call back the same day telling us what was needed. Our GMC Envoy runs like new again. We want to thank you again for your fast and amazing work. Also you always remember us and ask about our other cars. Your attention to detail is refreshing along with your matching Honest 1 name.

Great service! I've been taken care of by Junior here for a little over 1.5 years now. We always drive 45 min to an hour to have our company vehicle serviced here from South OC. Worth the drive to experience this level of service!
