$350k to $400k Mustang?

Just another Falcon, absolutely. With that I wholeheartedly agree.
The power steering on those things looked like it was cobbled together in somebody's back yard, with hoses always leaking and hanging down below the car.
The trunk floor was the top of the gas tank! When the Pinto came out with a similar design, they were roundly condemned as firebombs.
The backseats were basically vinyl stretched over the floor pan.
The fit and finish on them made Chrysler look like Bentleys by comparison.
Of course, the world is a big place, and there may be some numbskull who will pay that kind of money for it, but I doubt it. Not in my lifetime. Maybe Ford would pay for it, as a PR stunt, but a private party I doubt.
Well then, I guess you will just have to wait and see. What you want to believe doesn’t matter.
