He could, but I doubt very much he would get it. As has been said previously, when you hit the £10K+ mark you are getting beyond what the average Manta aficionado is willing or able to spend. I could point you to a few others that have been, or are up for higher figures and either didn't sell or go from dealer to dealer and still don't sell.
Until someone actually gets to have a good look at this particular car and can see what hiding underneath (or not) we are just talking hypothetical values. A current MOT would certainly help though. There's no MOT history online, so has been off the road for 15 years at least.
Of course, on the plus side it's a GTE coupe, and rare in black with the Chicago interior. Pretty sure solid black was dropped for the 87MY.
