Well it would be nice to see some pics of the Stamps. firewall tag showing the original color, motor stamp and trans stamp, rear end. Also is there any original paperwork included?
First things I notice about the pics:
-Great color with the vinyl roof, (make sure you verify.)
-RS, but as mentioned I don't see the vacuum lines, so converted to electric?
-aftermarket Hurst linkage installed
-The seats have been recovered, but very poorly. Not really pulled tight, and may need new foam.
Looks like a nice car, I would make sure the body is in really nice shape. The 4 speed is definitely a value adder of about 5-7k, so verify it is an original.
Let us know what else you are able to find out. You should be able to get a lot more information, before anyone has to make a trip to the dealer.
