Chris and the mechanics here at Honest-1 auto care are great. Worked on my 2007 Dodge Ram and got it running as good as new. Will definitely recommend if you need your vehicle worked on.

First time here and I will be back. Kevin Duncan took great care of me and my long list of work needed. He was upfront about everything I wanted, he didn't try to sell me work I didn't need. He is extemely knowledgable and the team was great. Very pleased with the whole experience, and would highly recommend them.

Was referred to this Honest One location, by a friend several years ago. The Customer Service is A+., and you can ask as many questions as you want. I have always gotten a clear and honest answer. The lounge is Super Comfortable and Sparkling Clean, as is the Restroom. They keep their promises. The work is A+. Their prices are competitive.
