Wish you had your high school car back?
I didn't have a car in high school - had to rely on borrowing my parents car when I needed wheels.
But I sure wish I had my first Mopar back! A '69 340 Swinger that I bought slightly used. That was a great car. Too bad I got stupid some years later and turned it into a race car to run NHRA Super Street. Even worse, I sold it years later. Would have made a fun car to put back on the street.
Currently building another '69 Dart with hopes of it finally seeing the street this year.
