After visiting my car dealer to determine if I had a nail in my tire and receiving horrible service at my dealer, a friend told me to take my car here. My dealer told me that I likely didn't have a nail in the tire if my detector light was not on at that moment and they made me make a two hour appointment for two days later. I called M-A Shell and was told to come over immediately. They located the nail and plugged the tire within 5 minutes. Dealer Price: 65.00 M-A Shell price: 0.00 Unless it is a warranty issue, I will always bring my car here. Great Service. Could not be happier. I have many friends who bring their high-end vehicles here.
