I had the same seat covers on my '87 Porsche. They're not bad. For an X I would paint/dye the centers so they aren't two tone. As for the carpet....I had an X with the same thing. I think it was originally a brown, but UV and weather turns it into... Well, you can see.Nicely done car, but WTF on that carpet color? Seat covers look like the "PULeather" ones sold on eBay.
+1The carpet does not look original to me. My ‘79 came with a brown “corn row” type, that does fade quite a bit over the tunnel. This looks like a closed loop style that someone tried to dye.
