Testimonials

On 2/20/2026 Todd Shores had this to say:
We live in Waukesha and have a vacation home in Easton. My truck started sputtering badly on our way up several years ago. It did not start the next day. Luckily our son also came up and could take us home in his truck. Called GMJ Monday morning. They had it towed to their shop for repair. I expected it would be many hundred $$. Especially under the circumstances. Turned out it was small bit of debris in the mass air sensor. Charged me just over $100. They could have taken advantage of my situation and charged us much more. I really appreciate their honesty. Testimonial written by Todd Shores on this site.

Very friendly and so helpful. They run a tight ship and we have been very happy with the service. They do go out of their way to make sure we understand what they did and it's done.
