This is a pic of a 78 mustang II mach 1 from the movie Mask.
Some folks in the interwebs claim its a 75 but they be wrong.
I'm about 80% certain that's my old car.
It was a very rare livery with the silver/black and smoked T tops and mach 1 detail.
It had a a gutless 302 2 bbl and 3 speed automatic, rated at 133 hp (SAE net)
Weight to HP ratio was 22.6 lbs/hp.
And it got around 17 mpg to boot.
