When does money outweigh sentimental value? 1968 notchback build thread

So my dad bought that in 1993. 71 charger RT, trackpack, 440 Magnum, 4 speed, Dana 60, with an air grabber.
So that enticed my mom to want something old and cool. Enter the barracuda, Which was bought in 1994. She drove it a little bit but it was too fast and smelled too old. So I bought it from her in 95, when I was 15.
My dad sold the charger a couple years ago. I offered him a break even of $6,200 which is what he paid for it in 93. Lol. He got decent money out of it.

Ahhhh, one of my bucket list cars....
