My GMC was at the collision dept for a water leak on the front passengers side. Apparently coming from the drainage tubing for the sunroof. The technician suggested that the tubing on both sides be replaced, and I TOTALLY agreed! I was informed only a few hours after dropping off the GMC as to the problem, the recommended fix, and the cost. All went well, everyone I dealt with was professional and pleasant! Never a problem dealing with STAR!
