What have you sold in the past that you now regret.

I generally don't sell stuff, therefore, no regrets.

[Innuendo]

I generally don't sell stuff, therefore, no regrets.

I generally fall into that category also. That said I have sold things that now would be worth a hell of a lot more cash.
I.E: Chev's, Pontiac, Monaros, Toranas, Panel Vans. In a way I regret selling my HQ 454 Big Block Van (but at the time it was time to part with it).
Same could be said of my LC 9/71 Bathurst Special GTR XU-1

Still without selling them when I did, I wouldn't be in the position I'm in today.
