  • 5 star review  The employees were so friendly! I had to get my starter replaced while I was there. They fixed it in a timely manner, offered me coffee, and on top of that offered to grab me lunch while I waited! They went over and beyond to make me feel comfortable. I will definitely go back for any car issues in the future! Thank you all for being so nice to me! That goes a long way in my book!

  • 5 star review  Anytime I have an issue or just need a check up I'm met with a friendly face and knowledgeable employees that can make the necessary repairs, and if they can't are able to direct me where I need to go. Love it!

  • 5 star review  We started taking our vehicles to Cintech when we owned a delivery company. They did a great job of keeping our vans on the road with quick efficient service. We've used them on all our personal vehicles for 15 years or more. They were even kind enough to "go through" a car that we were buying for our new 16 year old driver. They are the best
