I might offer this.
I grew up during the 60s-70s (well, maybe I never grew up). I built my own budget hot rods that would blow the doors off of any ‘new’ muscle car, stop light to stop light.
NOW, I’ve owned several CTS-Vs. Yes, 4 doors and automatic transmissions, both which I’d swore I would never own! They are insane fast. I had them programmed to over 600hp, they run on pump gas, I can run the a/c while flogging it, they handle like a roller coaster, they have WARRANTY, they have incredible sound systems, are a pleasure to drive and don’t pee oil all over the driveway and garage.
Now, I paid $800 for my 55 Chevy 2dr post with a 327/4speed in 1973. A new performance Corvette or Camaro was probably under $5k. Our money isn’t worth diddly today so it costs $45-100k today for a performance car, classic or new. The new I would love to drive every day, the classic, is art and will spend most of it’s golden years in the garage.
I’m am leaning heavily toward resto-mods. In the process of building a very radical 50 Merc and early Chevy Suburbans and pickups. I should say, “Having them built to my specs”, as I no longer have the desire or time to do it myself.
I can see ‘excellent examples’ of extreme classics and popular muscle cars retaining high values, like popular art work does. It’s a much more fun way to store and build wealth, than boring stocks, etc. Those cars that don’t fall into that category, will once again become the property of enthusiast, keeping in mind, they will still probably keep you ahead of inflation.
