I have seen a lot of coupes and am currently maintaining a sales price database, here is Haggerty's Condition 4:
"daily drivers, with flaws visible to the naked eye. The chrome might have pitting or scratches, the windshield might be chipped. Paintwork is imperfect, and perhaps the fender has a minor dent. The interior could have split seams or a cracked dash. No major parts are missing, but the wheels could differ from the originals, or the interior might not be stock. A #4 car can also be a deteriorated restoration. "Fair" is the one word that describes a Hagerty Price Guide #4 car"
Sorry to the seller, from the photos this coupe would be a stretch, starting with the fenders. Condition 5 is more accurate IMO without seeing it in the flesh. The underside pic also shows the bottom of A pillars rusting away along with rockers, bent rear bumper, interior in poor shape, is that rust at leading edge of body above trim strip?
