Client Testimonials

Griffin Muffler & Brake is awesome! I just moved to town and found them here on Google. They had my car in and out very quickly (within 6 hours), and they were very upfront and honest about the work being done on my car. They have a wonderful texting system that sends you reports on your car so you can easily see all the changes and charges. I would recommend them to anyone!
Rebecca Bennett
Great staff. Good solid work. Ive taken vehicles to them a few times. They always do a nice job of fixing things but what gets them the 5 stars is the staff. Everyone is so nice and helpful, its as if you are turning your vehicle over to family, only these guys know what they are doing.
