They were able to find and fix a rare issue, on my Van. They keep a clean shop. They communicate well and are friendly. I give them 5 Stars out of 5. I will return, if the need arises.

I had no appointment, but I did have a "clanking" vehicle on a Saturday morning. The manager not only was very polite and efficient but had it fixed quickly. The heat shield had come loose and it only needed a bolt put in but he did not charge me because it was so simple a fix. What he did get is a customer, EVERY TIME I have a muffler problem!

My family has used Tuffy since I moved up to Michigan a few years ago and we couldn't be happier with their customer service, repairs and honesty. They are very fair on prices and we have had all of our vehicles inspected by them before purchasing and we couldn't be happier!

Today I heard a rattle under my car. I stopped in at Tuffy, expecting the worst. The mechanic quickly put the car on a hoist, showed me the problem. It was an unnecessary part that could be removed in 5 minutes. Done. No charge. I'll use them again when in need.
