It's a very odd car. It has 289FIA type exhausts, they exit underneath the sie of the car (if you know what I mean), its got quick jack over-riders, usually they have the chrome, "fang" shaped bumperettes, the fuel filler is in the center of the rear deck (as far as i know, they were only mounted on the right rear fender(never the left, regardless if the car was left or right hand drive) or slightly off center on the rear deck). It also has a bonnet scoop, and smaller air vents in the bonnet. It has small brake ducts in the front next to the nose, it has a hideous front bumper, combined with the quick jacks which is really weird, and it has funny stone guards on the front wheel arches.
I'd say it's a blueprint of the racing one pictured in reply #8, only it has a full windscreen and a front bumper, and stone guards. It could possibly be a BP of an ex-racer, with the modifications above added by its owner.
Can somebody please change the name to SHELBY Cobra. There is no such thing as an AC Cobra (well, there was for a year or 2 but they stopped using the name). It was Shelby who first called the car a Cobra, after the name came to him in a dream, and he has the naming rights (or some sort of other legal mumbo jumbo) to the name.
