  • Very friendly service up front and from the techs. Was referred here by a friend and found a longtime shop for all my vehicles! I highly recommend Simon's! Affordable and great people to talk to while you wait. Even a very pretty lady up front. ;)

  • I have been a customer at Simons for a long time. When I drop off my vehicle I have confidence they will not only do quality work, but they do honest work. They don't try to add on unnecessary repairs. They check things out and let you know what needs to done now or in the near future so you can plan the next visit. I never go anywhere else.

  • I loved my experience with Simons. I was hesitant from the reviews but I have no clue what those bad reviews were referring to!! Because the staff was friendly, the techs were thorough, I did not have to wait hours to get in, the lady at the counter asked me how my service was and cared for my opinions, it was clean, and best of all they were the cheapest I could find in this area!!!

  • They do quality work at an affordable price! When both of my lights on my chevy went out, everybody wanted to charge me $250 an hour for an unspecified amount of hours to fix the problem.

    Not Simon's!!

    They said we will check it out for a $35 non refundable, and tell you what going on, and how much it will coat to fix! an hour later they said it will cost a Total Of About $102! i paid them immediately! and drove away happy!! Now That's Integrity! Honesty from an auto mechanic place! Unbelievable.

    Those dishonest other places wanted $250/hr. Even Bill Gates And Oprah Winfrey would have rejected that!

    In Ill go to Simon's for full auto service

  • Great service! I am from out of town and was recommended here from the Walmart employees. I'm so glad I was. I would definitely use again.
