My Dad used to have a 1967 Mustang fast-back, very much like Steve McQueen’s in “Bullitt” (though that one was a '68).
He let me drive it after I got my license, so it was essentially “my” car during my Junior and Senior years in High School (1980-1981).
I am ashamed to admit that I did not appreciate what I had. Instead of realizing what an awesome car I was allowed to drive, I was mostly frustrated by its quirks - the carburetor was finicky, it flooded easily, and the gas gauge didn’t work. Dad tried to use that car to pass some of his mechanical mastery down to me, but it didn’t take.
If I had it to do over again, I would have been much more reverent of that machine, and maybe even tried to buy it from him when I started working (he kept it until I was about 25 or so).
