People love to talk about how cars are only important to one generation. That doesn't always apply to Porsches. I've now buying large collections of 356's from guys who I call the 2nd generation, who got into 356's in the 70s, they are all in their late 60s now, sometimes early 70s. But they weren't the original owners, just large groups of guys who liked Porsches, and they have kept changing hands since.
One thing I think you will see in the next few decades, lots of Porsche getting electric motors. Some will have the gas motor dropped out, some I think will be restored and forgoing the gas motor. I just sold a 912 to a guy in Chile, he is going all electric.
Don't believe me on the universal appeal of Porsche, start driving your car to the grocery store, and you'll see what I mean, people of all ages love it!
