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

We all love muscle cars/streetrods/ mopars, fords, chevys and all the rest. But the world is changing...and starting to leave us in the dust. When will it happen...who knows ? But chevy has made an electric camaro, dodge is working to electrifty the challenger. Like it or not , i's coming.
I'm not preaching doom and gloom. But just wondering how long before our 60's-70's performance cars loose there value ?
Who will want to buy the average muscle car when affordable gas is had to find or buy ?
I'm not talking about rare perfect mopars...but the cars that most of us own right now.
I have a 1933 DeSoto 3 window coupe with a 426 hemi. And have not driven it for some time. I think about selling it all the time...But I built everything. Frame/engine.trans.I built the complete car. I do not sell it because I still like the car. But I do not have plans to do the things it needs to make it a better car.
I look at it like cash in the bank...someday, when and if I sell it. Sell it to soon..for less money. Wait to long (hopefully a long time from now) and you may not be able to give an old internal combustion engine away.
At what point do you sell ? How long before the electric car crash...I'm sure a lot of you think that I'm crazy...But the day will come, when nobody would even call about the mopar that's in your garage...unless you've converted over to electric power.
Trust me I hope I'm long gone before things get that bad. But the world is changing. And it's not going to wait for us. There's an old saying "adapt - or die "
Does anyone else wonder how long before the bottom falls out for the values of our muscle cars ?
OK let me have all the smack talk. But if your honest with yourself, you know that the day will come when you think to yourself...damn, I should have sold my car about 5 years ago, when the prices were the highest that they ever were.

Go Bag and AR ready for the "DAY":elmer:
