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

Investing in old classic cars is for the rich and want to be famous IMO. We have discussed on this forum before about these cars as investments and majority feel this is a hobby and IF someone wants a good classic car investment, go to the experts and buy into Porche maybe. For 99% of us it is a hobby.
I have restored many "good " mopars since mid 80's, and here is an example of what is. Back in say 'early mid to later 70s I cold buy a complete 69 Roadrunner for $1000-1500,NO, 99% of them were NOT # matching, yes real RR but the original engine was long) and after I did an ALMOST nut and bolt resto, as in perfect body/paint, rebuilt engine trans, new legendary int, maybe a rebuilt front end if needed, a good rear, new or god tire, new exhaust, it would bring about $7500-8000. Sure I have seen guys buy it from me, do nothing and flip it for another $1-3000 in another part of the country. I had about in it what I sold it for.
Fast forward to today, you can't even find a decent complete 69 383 Roadrunner project, for Less than $5000 and it will generally be crap, and need every body panel replaced. Same resto today with me again doing all the work except body/paint, will me having more like $25000 in it. Realistically what it is worth. Sure someone somewhere could sell it for $27-30000 maybe.
If we went back to the same period of mid 70;s a comlete AAR cuda project could be had for around $5-7000 and restored for the same $ pretty much as that 383 Runner. Fast forward to today, what are they going for?, but again too what would a AAR project car cost today also? Point is the very rare and best examples are cars that "might" be worth more, 1 or 2 or 3 decades down the road!!!
If someone wants an investment car, they better have a crystal ball and buy into the top cars of the top brands and models.
Otherwise, just enjoy the hobby,.... it is a money hole.
