CL find... 68 GTS
Prices have always varied on similar cars. It's all speculation until someone ponies up some cash and the seller agrees to that price and the papers are signed.
It's true that for much of it, like the seat covers, don't much matter since they need replacing either way, but usable vs unusable (for a driver) will still make some difference in price to some people. It's real hard to tell from the pictures, but the maroon car appears to me to be in overall better condition, and more complete, plus we know it's numbers matching. All that adds some value. How much? Who knows. Until the papers are signed, all speculation.
