Once I started driving the black one on a regular basis (ie; garage queen no more), the central Calif. heat took a quick toll on the headliner. I took it in to a local auto upholstery shop and the owner told me to let it fail almost fully, then take it in. He said he could gauge the overall failure more accurately. Sure enough, he said there were two "hot spots" in the fact. glue on each side of the inner roof crease line. He upgraded the headliner (almost identical to factory and upgraded the glue) and it came out great! No problems in our recent 100 degree plus spell that we had (that's why our raisins turn out so good. lol). $210 out the door. The graphite has just started to pull very slightly by the visors, but for now, it's the garage queen.
