Should you buy, sell, or hold these classic Mopars?

I have owned many old Mopars since the mid 80's, everything pretty much. I rarely ever mad a profit on any restored car. I did good to just get my $ back out of it, and I had good project cars bought cheaper than most. I made some profit on selling projects way back then, as I simple cleaned them up and got them running. But good project cars were abundant and I could find good ones where I could sell them at a fair price and me and the buyer were happy. Noone bak then wanted 318 anything or even dusters or hardly a 340 A body even. The ones I made the best $ on were rare cars like AAR Cudas, a few hemi projects, 440-6 cars, that the seller could not sell,and called me, and I drove 500-800 mi for the car. Sure, if I had sat on them for decades I would have sold well, but I turned them and someone got them that needed them. Glad they went to good homes. I never regret not being well off.
I have never sold any car for less $ than I had in it, many I barely broke even, and not counting any of my labor. It has strictly been a hobby for me the last 18 years. But I never buy any project that I don't think I will at least break even on when I let it go, but now days I do all the work, even the body/paint. It will be a decent looking driver with all rust repaired, and usually just a decent running stock motor, usually missing the door panels, headliner carpet and ripped seats!! lol
I am sure people can buy a restored car at a good price, and find someone to pay a little more. Takes a good eye, a lot of friends and networking, and then being in the right paart of the ountry to find a buyer to pay top retail.
I rather trade horses and goats!
