Very Impressed!

Mark George
Customer Review
I am very impressed. Clay and his team go above and beyond to give the best product possible. I was in for a FASS system install. They found and fixed a problem with the FASS wiring harness. They found and fixed a possible fire hazard on a battery cable I installed. I purchased a light bar and CMC installed the coolest switch in the perfect location. I'll be back for a rear light bar. Great service at a great price. The bill was exactly what I thought it would be.
