Testimonials

On 8/22/2025 Richard Comer had this to say:
Had emission repairs on 2018 Chevy Equinox 1.6L L4 Diesel. Repairs done within a few days. Price VERY reasonable. Staff friendly and listened to what I had to say. I will use them again.

On 5/24/2025 Nikolce Jolakoski had this to say:
Took my 2016 F350 dually to J&M, was experiencing the “death wobble” that progressively got worse. Took it to another shop prior told me everything was fine made it sound like I was crazy. Finally took it to J&M, wish I had done it sooner. Took the time to explain everything and show me things on my truck, and most importantly fixed the issue. Highly recommend. Only place I’ll take my stuff going forward.
