Haven't seen this one advertised for a few years now, but it appears to still be with the same guy who had it for sale over and over and over a number of years ago, usually on eBay. Listing pictures from years ago always had it looking to be very clean and in nice shape.....not the case any more . Looks like it has been stored outside for a long time with the windows open.

I love how it is listed as "matching numbers". Uhhh, yeah, if you can overlook the fact that the VIN indicates that it's a Custom Coupe but the Trim Tag shows it to be a Sport Coupe
