For an anecdote in a different direction, my father bought a Ford model T a few years ago. Now, "classic" cars of the 60's and 70's are still very popular among those who lived through that time. Maybe your family had one or there was a particular car you wished you could have had. I don't think the model T works like that. Next year, all model T's will be 100 years old, so even if you are 95 today, when you started driving, the newest model T would have been a 20 year old car.

I've been with him to a couple of the local model T club meetings. The demographics are interesting. I was the youngest person there. My dad (late 60's) was the second youngest. But you have to remember that nobody alive, even the real geezers, has experienced a time when a Ford model T wasn't an old car. So by all means, it seems like this hobby should have died out decades ago, even as it continues to die out today. Very strange.

As it stands, it looks like a decent condition Model T can be bought these days for 10-20K, only a bit more than the inflation-adjusted original price. But, I don't really know what the collectors market was like at peak nostalgia.
