I read about young people bidding up the price of '80's & '90's cars at the auctions, but don't see many young people at car events or driving their cool cars. I own two German cars from the 1980's, an American car from the early 1990's and a Miata from the early 21st Century. All youngtimer cars and I'm in my late sixties.
I spent decades restoring and driving '60's cars and simply grew tired of them. They're easy to work on, but break a lot more often than newer cars. An E30 BMW is more fun to drive than any '60's car that I can think of. They are a little more difficult to repair, however, but worth the effort. As an older person, I can also afford expensive German repair parts. So, yes. Old men are also getting into youngtimer cars.
