This is far more true than I think people give credit for. I grew up in the early 00s. Aside from the barracuda which I have a sentimental attachement to, I really don't care about cars from before like 96 and I think a lot of dudes my age feel the same way. We love cars that we grew up with which are "newer". I have a couple old cars that are cool that I'd love to own like a 66 impala or a 70 camaro but most of the cars I want are around my age or younger. A 91 ZR1, CTSV, Commodore (chevy SS, G8, Caprice), 300 srt, magnum srt8, E63 AMG, 96 Toyota Century, pontiac fiero etc. Those are the cars that I'm like Yesssss for. Also, apparently Chevys lol. I do really appreciate older cars for how easy they are to work on, but my interests are mostly about the newer ones. My next car is going to be a commodore or an E63 not an old one. Honestly project cars just require a huge time commitment or money neither of which I have raising 2 very young kids. Sim racing is cheap, has a one time build cost and provides me with ton's of driving on circuits I'll never be able to go to irl. If money were no object I'd have multiple projects but I don't.
There was a guy here who had that attitude saying "old mopars aren't for young people." He had a yellow dart with QA1 suspension. People like him are part of the reason no one wants old cars. We're like fine, then **** you.
