"I would like to give a HUGE thank you to Frank from Grandma’s Speed Shop for fixing my flat tire today! Good Samaritans are angels God sends your way to help! I was waiting for roadside service…. The standard half hour to 45 min wait and a pickup truck pulls up next to me and asks me if I needed help. He was going to put my donut spare on but when i told him I had a 2 hour drive to Kalamazoo, he said, Nooo! I’m going to try and patch up your tire, its not a good idea to travel that far on a donut! Well, he fixed my tire for me, in the freezing cold rain and was sooo kind every step of the way! Thank you Frank!"

"These guys know their stuff! I had a bunch of major work done by them. I am Completely satisfied and will be a customer for life. They are honest, and a group of great guys. The saying " you get what you pay for" is absolutely true. I can't recommend them more!!"
