After over 40+ years in the auto repair/restoration business, specializing in the upholstery/trimmer. It is my observation that I would have to agree with what Coralsnake said. My Shelby sat for 40 years with 72,000 original miles with only a repaint. The car is Gulfstream Aqua, white interior, with only red inserts in the carpet. The carpet had never been out of the car before, as when i pulled it out all the underlayment was still in place and undisturbed, all the correct seatbelt washers and sealer was there and in the correct order, plus the seat bolts under the car only left one semi circle mark left by the nut/washer. the only time I have seen white seats with Red inserts or Black carpet with four black inserts was when they were made by an aftermarket company. Just my observation.
