What customers said about general repairs & maintenance
Richins Car ServiceThese guys are great, honest, friendly and located in a super convenient area! Kelly looked over a new used car I just purchased and gave a better summary of the car than the pre-purchase inspection I paid for somewhere else. He did it as a courtesy while he was doing some work I brought it in for on the CV axle…
Richins Car ServiceI've been taking my cars to Richens for about ten years now, and they’ve never let me down. I really appreciate their honesty, great work, and fair prices. I highly recommend them and will keep going back whenever I need service. Thanks.

Richins Car ServiceI was referred to Richins Auto via a family member and I’m so happy I was. They are kind, honest and fun! They explained exactly what needed to be fixed and made sure I understood before moving forward with the job. The work was completed in half a day. I would recommend these guys to anyone!
