1973 Ford Mustang Fastback?
I had one (my wife had to have it)
It was longer, lower and wider than the sixties.
It has a very wide engine compartment and would fit any engine you wanted. I put a 428 in mine, eventually.
The interior is roomy (for a 'stang).
It was more for older and fatter folks(like me).
The visibility was miserable, despite the great big back window it was hard to see to back up.
If you are a big guy, you might like the '73.
Mine was front heavy and would not do corners well, but it would burn up tires, if you like that stuff.
