Is it time to sell the Citroen BX 16V? A last drive, or reviving the love?

I love the 16V BX and we've had this one for a while. It's a great daily driver, a unique car and rare with it. But it's been sat stagnant for a few months now we are in winter. I mentioned in the BX OC the other day that I was thinking of moving it on, and immediately my inbox lit up. But one man in particular ticked the boxes as the "right" guy to buy it. But when I dug it out today to get him some photos across, I was filled with regret and confusion. So where do we go? Do I move it on and start new adventures, or keep the car I love and continue to enjoy it?
