future value of classic performance cars,when to bail out, before the crash?

I am not in this hobby for the money. Never have been.
As long as i can remember, i've been a car guy.
The pleasure i get is from working on them, and especially driving them.
I remember back in my youth when these 50's to '80s cars were bought for the sole purpose of having a good time modifying and racing them, cruising, daily driving, and what have you.
Most people weren't concerned about their rarity and originality, just that they were cool or they got them from point A to point B.
I also remember a time when you could buy them cheap (comparatively speaking) and run the crap out of them, blow them up, and then fix them in your driveway.
The mind set back then was the car was a basis for modification to suit your tastes or need for speed.
Now people get all wrapped up in what's it worth and originality............yada yada yada.
I have always said the satisfaction you get out of owning one of these older cars is the ''Smiles per Gallon'' that it gives you when you take it out and drive it.
Sure, prices have gone up a lot since the old days, but i think where a lot of people miss the boat is that they're too worried about harming the value of these ''rare'' cars and not driving and enjoying them.
I am a product of my time when growing up with these cars was the only thing i knew.
Times have changed of course, but have they really?
You can go down to a dealer and buy a new (or used) muscle car for what i think is a reasonable price, modify it or do what you like to make it your own.
Just like in the old days.
It really works out that nothing has really changed, just that it's come full circle.
There will always be a need and a market for performance cars and trucks, and the worry of the internal combustion engine becoming obsolete is in my opinion is hogwash.
Electric and hybrid vehicles will have their place, but so will the gas and diesel powered vehicles as well.
If you look at it sensibly, there are millions of vehicles of all types that run on gas and diesel (fossil fuels) so i don't see them being phased out overnight.
Maybe in a few hundred years, but not anytime soon!
BTW, we can thank the higher prices of the 50's to '80s muscle cars to a great assortment and supply of parts to restore them.
I remember in the early '80s when virtually nothing was available in the after market for old Mopars other than mechanical parts only.
Would there be an availability of these parts now if it wasn't possible for these manufactures to make a profit and supply a demand?
I don't think so.
Some food for thought................
