It was item #191 and was described as a "Tribute" vehicle.
S/N stamped on metal tag in engine bay is"CSX3032" , I copied it down.
(I was sorry I didn't have my camera)
Metal plate also had SHELBY MOTOR VEHICLES, or something like that. (Didn't copy that as I had to borrow a pen & paper), but S/N definately correct.
Looking in the above noted thread this appears to be the car I saw.
Location of battery, fuse block, gold palted webbers etc all the same. CSX3032 on Ebay......
