Porsche : 944 SPORT (DOHC) in Porsche | eBay Motors
But I noticed it has cloth, including the doorpanels (you can see it on the rear seat backs too). But it isn't Plaid (which apparently, although super rare, was optional on any Porsche at the time), and it isn't the more common "Script". It has regular cloth. I've never seen this before. Looks original though?
Take care,
