Forgot last of many RWD cars at least for GM.
I would never put those cars into the "collectible" category. First, the later half of the 70's and most of the 80's are nothing to talk about when it came to American cars in design or build quality. Second, when one looks at the number of those cars sold they were no where near home runs in the amount of units sold. If few people wanted them back at that time then how many people are going to want them now who have memories of them? How many are alive, how many are healthy enough and how many have the room given that seniors tend to downsize. And yes we are seniors. I will repeat once again and that is those who are under 40, except the 0.01% who do like them, the rest aren't interested. At Mopar shows out here they show up in new Chrysler 300 cars many modded out.
Got to remember we are baby boomers for the most part. Now how many people collected cars in the 40s? How many in the 50s? How many in the 60s and even how many in the 70s? Car collecting on such a large scale as today is baby boomer driven. So it is like a fad. Just a fad that will take longer to die out. We do have a tendency to project our bias onto the next generations. Yet they will form their own bias toward cars. When I have a 16 year old grandson, in 2040s, I am sure even my Mustang will mean nothing. Technology is now changing things so fast I couldn't even imagine what I'll see in 2020. Cars as we know them, gasoline as we know it, among other things could possibly cause all our cars to become garage queens by 2030.
There is a fellow out here who has listed 8 mid-50s Pontiacs for sale this whole past year over and over and over again. No one is biting and I suspect no one will. I was 3 years old then, have no memory of them and kind of go meh. For the most part their heyday has past and so will ours.
