I recently took possession of my late grandmother'so 1978 Grand Prix LJ. The inside is mint. I don't think the passenger or rear seats were ever used before I got it. It's all green including the interior. I looked into selling it but found it is not really worth enough for me to let it go just yet..and it is really growing on me. It rides better than anything. I am wanting to fix up the outside to match the amazing condition of the interior. The paint has normal fading on the hood, roof, and trunk. The landau top is slightly darker green and needs to be replaced. The problem is, the upholstery places say the vinyl color is discontinued. Anyone know if I have other options?
