Well if it is fishy, they have Carfax reports as well, looks like form 2 different dealers, one is Chevrolet, but maybe they changed brands over the last 11 years? My guess is someone actually bought a couple of them and stored them from new down there.
And the pictures aren't exactly the same, there is a mark on the floor, and the valves are in different position. Looks like they have a good setup for photos!
