This is mostly a case of the next car up.
Mopars for a long time were depressed in price but the Hemi and big blocks took off. Today the small blocks are the next car up as you can still get a decent price for now but as demand grows.
Same for the late 70's Trans Am. The early cars were doing well as a 455 SD or TA was a big buck car. The 75 and later cars were not in big demand. Today they are the next car up for GM.
I expect the late 70's Z/28 will come into play before long as they are much lower than they should be. My guess for the next car up will be a Monte SS Aero before long. Same for the GP 2+2 but it will be a while.
At Ford the 70's were not good. The Mustang II just never has excited many and only a rare few special edition V8 models hold much interest. But give it a couple years and the market for un molested stock Fox platform Mustangs will come with a vengeance. The key will be un modified models just as the GN will demand top dollar.
The coming wild card is the Indy Pace Car GTA Turbo. This car is one for the ages with the model and the engine in low numbers. A tough car to restore so stock low mile cars will be key.
As for the market when ever the market gets volatile the collector car market moves as people more their money from the market. They look for investments that they can maintain till the market returns. We may see some action for a couple years as the economy to return. I expect three years before we see much change.
As for many of these new more modern cars Unrestored and low miles will be key. Also if they are modified are the parts highly desirable parts from the era that are hard to find today in good shape. Things like a Herb Adams VSE suspension on a TA would be a good find. These kinds of mods are going to be the Shelby like things of this era. Era correct Paxton for a Mustang Fox body will be popular too. The 80's Mopars will struggle unless it has a Shelby tag. Then it still will be a good value. A late 70's Little Red Express or Warlock would be a good find in good condition. Also easy to restore vs many cars.
Just my take.
I think that is a valid view, but I agree with some of it and see a different perspective on other parts, and some of it is old news to the close watcher.
I think that we are seeing a legitimate resurgence (how long it'll last is a big question mark though). Yes, rising tides raise all ships, but it is a hard argument to make in my mind that a 318 or 360 MOPAR is primed to pop because 383 and 440 cars are up... 340s are a different story, those have some performance pedigree and they have seen growth because of it.
I've been watching the market very closely for years and some of the cars noted have been on the rise for a while. Late 70s Z/28s already saw a boost, just not as much as Bandit T/A's, which are a bit more "muscly" anyway. But mid to late 70s T/A's (especially 77-81) have been as if not more expensive (in certain configurations) than the early 70s for a few years now and 89 Turbo T/A's have came up in value a few years ago and have been bouncing up and down for a while.
Now the Monte Carlo and Grand Prix aero cars... I think there is some validity there. I think they're a bargain given what they are.
But really, everything is up. Some of it might be a rising tide, other side is that it is newfound recognition.
The 79 TA will do fine if it is a Pontiac 400 with 4 speed. Limited numbers here are key to the last of a kind. The Olds engine cars not so much.
The RAD Wood deal is growing and this will help the 80’s cars.

Very nice. The '04s did need a little something more. The 7.0 upgrade was a nice touch. Here in Canada these cars are really rare which makes them even more of a surprise to unsuspecting Camaros.
