Testimonials

On 2/20/2026 Michael Bochenek had this to say:
This is my 4th time having John at ProMechanics repair my cars. One time for my son, 2 repairs for my daughter’s cars and now for our 2012 gmc terrain. All repairs have been completed successfully the first time. If you are looking for a trustworthy, experienced and professional shop, look no further. I highly recommend ProMechanics. I had to pull out terrain out of another shop due to lack of professionalism and knowledge of car repair and outrageously expensive estimate. I only brought terrain there due to convenience of location. If I could have, I would have brought it to ProMechanics the first time. With John, I received an accurate fair estimate the same day and after the first inspection. That’s how auto repair shops should do business. I have and always will recommend my friends go to ProMechanics for service. Thank you John!
