I had that same car. My dad gave it to me when I was 17 (in 1977). I had no idea why until I had to fill it with gas.
Not much on corners but on the straights it was a rocket on rails.
Then I bought a 1973 BMW 2002 and promptly rolled it the first weekend I had it.
In 1988, my 1973 LTD was stolen while parked in front of the University of Southern California. The door was locked and I had the key, so someone was determined to steal the car. probably became a taxicab in Tijuana.
I replaced it with a 1984 Ford Crown Victoria that was essentially a lemon.
