Man,... I had a 73 Duster...
Wasn't fast though...no 318...just a sturdy 225 slant six...
It was a gutless dawg, but you couldn't kill it.
Once blew a radiator hose on the way back from Vegas, dead broke, topped off the water and prayed...drove 90 miles, got to a station where a guy traded me a hose for my walkman..
Opened the hood and the engine block was still glowing.
Sat for a few hours so it could cool before I added fluid...drove back to mesa just fine...car lasted me 3 more years before it was handed down to the wife's cousin...
Damn 225 slant is unkillable
Oh, and the movie looks great too. Even aside from the car
