I have a 2000 GTP with a grayish interior; the driver's side seat on the door side is cracking up. When I bought the car, a piece of the vinyl was missing, maybe 3 inches long. Is there someplace where I can buy a piece of vinyl to glue over the damage area? Something near the GM slate blue or charcoal or whatever they call it. A patch the same color would look better than a hole and crack.
