My daughter took possession of a 2010 M-B GLK350 when I purchased a 2016 C300 from your dealership. Earlier this Fall, she lost confidence in her brakes, and we had it towed to your dealership. Next day, we received an estimate of $4,800 to have the brake lines replaced. I discussed this with my local repair shop in Chapin, and they could not understand neither the estimate, nor the pricing. We paid your "diagnostic fee" to get the care released and towed to Chapin. We then waited 3.5 days, while my local repair shop awaited your parts estimate, which never arrived. Ultimately, they were forced to obtain the M-B parts from an out of state dealer, and not only replaced the brake lines, but also the brake pads and rotors, all the way around. Final cost, $1700, total. Due to this situation, you not only lost my wife an I as a customer, but also my daughter, and the local repair shop.
