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

The muscle car is not ever going away pop culture loves nostalgia they are already doing rest mods with electric motors. Dual motors at that with AC and DC. After the Tesla kick some *** rich guys are putting that in their classics. For about a 120k you can too for now. In the near future the technology will be cheap like buying a TV now.
Fast with electric drivetrains yes. But boring as heck. Who wants a slick looking muscle car that doesnt come "alive" with a throaty idle and a "heartbeat" when you twist the key. The sounds, smells, and vibrations are all part of the ownership experience. Not just the look of the car and feel of acceleration. Winding it out, clutching and shifting, getting rubber out of second gear, that is all part of the experience of owning one of these cars. It always was, and thats the draw to them. People just seem to love the rawness and primitive brutishness of em wrapped in a nicely styled shell. That is why the new Challenger sells so well after 10 years of production with the gen 3 Hemi in all flavors.

Awhile ago i saw a video of an electrified 67 mustang fastback. Yes the acceleration was very impressive. Supercar worthy 1,000 shaft HP. He uses a 9" rear, and boils the hides at will too. But its whisper quiet, and when you lightly step on the "volt pedal" i imagine you hear relays clicking and the whir of the electric motor, not unlike driving a really souped up club car golf cart. I bet its fun to drive from the acceleration standpoint, but without the sounds, feel, and smells that are supposed to go along with it, after awhile boring.
