5-Star Review by Dusty Gregory

My Dodge 5500 was over heating when I came north with a custom trailer.  Locke had some unique trouble shooting to do but kept me informed, and was above fair when it was concluded.  Many hours were expended figuring out the issues but they were finally located and fixed above and beyond. Thank you Locke auto for getting me home by the weekend.

5-Star Review by Chris Schumacher

I brought my diesel truck in for service based on a recommendation from a family member. It had a number of issues and they addressed them all quickly and professionally. Might be the nicest waiting room and service area I’ve ever seen. They even ran me home to Mishawaka when we realized they would need the truck overnight. Good folks. Give em a try.

5-Star Review by Rachel Mitschelen

Our previous mechanic retired and we were looking for a new place. We seen the advertisement and decided to try it out. I took my truck to them and they gave it An inspection and checked the repair that I needed. We were able to have the repair done in a timely manner and it was done a very fair price. They were great at communicating with us!
