5 star review by Hillary Baron

“HM Motor Works is a great garage. I wish I would have known about them sooner. The staff it top notch and the work is done right....the first time! They know there stuff and keep you informed with no surprises. The prices are very reasonable. Which goes to show they do know what they are doing because you don't get charged for trial and error time when trying to repair the problem which happens at many repair shops. I will be going back to HM for all my auto needs.”

“I’ve been using HM Motor Works for a while now. I go to them because they are always honest about the work that’s needed. They don’t try to upsell me on extra work. Plus their prices are fair and much cheaper than the dealership. I’ll continue to go there.”

“Helen, Rick and the crew do it all. I let them know I was doing a track day and needed an inspection report. Not only did they complete the inspection but gave me some advice and pointers for maintaining the car as well. Can’t say enough about how good HM is.”
