You would think so, but there's a certain subset of zoomers who are _very_ into older cars, especially pre-mid-1990s cars.
Especially here in the Southeastern US... 90% of the time I see an old vette, NA miata, old civics, preludes, E36s, etc...it's some early 20s dude and they've done all the wrenching themselves and/or with their friends/dads. It's interesting to pay attention to the cars you don't see though -- the cars my generation absolutely destroyed -- Dodge Neons, 240SX and Turbobricks.
Most of the high-school and college aged dudes in my area are driving something 20 years old or more and it's not for lack of money -- they've done some _beautiful_ and expensive restorations on these cars.
When I brought my RX-7 home after getting rebuilt I had a gathering of teens at my door wanting to check it out.
It's mainly city kids who aren't interested in cars.
