The car you wish you would have kept?

Since I'm currently building a '69 Dart to replace the one I stupidly sold years ago, I'll go with the '70 Charger 500 we sold back in 1974 when we bought a new car ('74 TransAm, Buccaneer red with black interior and a 455).
The Charger was beautiful...triple black (paint, interior and vinyl top) with aluminum slot mags and L60-15 rear tires.
Another stupid decision from the past.
