Please tell me you're not going to argue about Hemi being the exception on a Mopar site.
And I thought I was **** retentive....LOL...
To answer the OPs question, the market for these old cars is and always will be cyclical. They will go up and down in value with time and there are many factors that will and have effect what happens as has been discussed in detail in this thread. The bottom line is I do not have a crystal ball and who knows. The best thing you can do is buy what you like and will enjoy and drive it without consideration as to its future value.
I will not argue the definition of muscle car as it has been argued for years with no definative outcome. I will however argue lumping compacts and sub-compacts into a catagory of Pony cars. Pony cars are ONLY the cars that were purposely built back in their first generation to compete with the Mustang that itself was often called the pony car. Next the Camaro, Firebird, Barracudas, and later E bodies.
Anybody that thinks a Dart, Nova, Comet, Falcon, Maverick, Pinto, Vega, etc. no matter the derivative of THEIR name is a pony car then tey are likely want-a-bees trying to attach themselves (their cars) into another group of cars that they find more appealing.
I'm not arguing about anything. I'm pointing out the flaw in your specific definition of a muscle car and illustrating why the term cannot be defined.
For every definition offered, there is a contradiction or exception. This is why there has never been and can never be a definition of a muscle car. We all know what one is but we can't define it.
If you allow one exception to a definition, in your case a Hemi, then you do not have a definition. You have a guideline or general rule of thumb. A definition is finite.
I think that with few exceptions, it's all about the demographics. I was fortunate enough to be brought up in the 50's and 60's car culture with dragstrips, street racing a 62 409 and dragracing a 63 MW.
This is not the same world I grew up in where I could fuel the Plymouth up with Chevron Custom Supreme 104 @
$1.06/ Gal and have fun.
Now it seems most of the kids (with a few exceptions) are into their Fart cans and I don't see any changes coming down the pike.
With the fuel prices, a hostile EPA, an administration bent on Wind and solar, devaluing the dollar, things are going to get real ugly. Less people will have enough disposable income to afford such a luxury much less afford the fuel.
Hell just look at what it takes for a family to survive now?I think that there will always be a market for the higher end investment cars but the run of the mill "Muscle cars"
are going to have to take a hit.
"Just grasping at another chance to be wrong".
What about the fastest car in 1978? A TRUCK. Surely it fits the definition. Faster than a 78 queervette.
