With few exceptions, if adults are drawn to their parents old car(s) at all, it's not because thee car is otherwise inherently 'cool' to them or their peers... They're primarily drawn to the car because of the memories they made with their parents. What the car is matters far less than what you did with it. Case in point:

My father had a 1993 Ford Explorer that I recall fondly. I passed my driver's test in it. It went on every camping trip. It had probably seen more mountains than I had at the time of it's passing (2009, take one guess as to why). Today it would be a pretty interesting car to have, but maybe only because 1st gens are rare to see on the road.
...There is probably a deeper reason than the rarity that you find 1st gen Explorers specifically to be as interesting as you do. In addition to TR6's, I have an odd soft spot in my heart for Isuzu Trooper II's and 3rd Gen Caravan's as well, all for the same reasons. But I wouldn't actually give up one of the limited spots in my driveway/garage for either of the latter two if they were given to me. At this point I would on the former, but I can't say that I always would have had the combined desire and ability to... It's still not what I would go out and buy for myself, and I'm honestly not sure how long I could justify even a TR6 for nostalgias sale.
Which brings me to the kids also need to be old enough to appreciate the nostalgia and memories, in addition to the space to store it, which they will most likely not be able to do until at least after they are well into 'adulting' themselves. Such cars generally make terrible primary, or even regular use, vehicles because of what inevitably happens to most anything that sees appliance usage.
I bought a cheap 05 Mustang GT convertible (manual) for this purpose. My girls loved it. It got totaled less than 2 months later. They'll never remember it and have no special appreciation for them. I bought a cheap 128i convertible ('rare' sport/manual combo) to fill that role now. They love it. If it too doesn't get totaled, I have no doubt they'll have an odd soft spot in their hearts for E88 128i's... But I have no delusions that they'll specifically want one, let alone have the desire and ability to take possession of this particular one (which will at best be 'well worn by then) when they're ready to head out on their own.
Both girls have also shown interest in helping me work on my cars, including the Locost whenever I get back to it. Working on a project together should also build this type of connection. Perhaps my project(s), but more so as they get older, I want to engage them in their own projects of their own interest that we create memories working on together.
So I'm going to boil this down to: Buy whatever will allow you to share the type of experiences and create the type of memories that will forever connect you with your kids.
