There’s plenty of affordable vintage cars out there, so even if a lot of cars are now priced to the stratosphere, not all are.
If you won’t be happy unless you can buy a hemi Superbird, and you’re not rich, you need a new hobby as you’re priced out! But otherwise there are interesting cars out there for under $20 grand or even 10 grand.
I split my time last year going to cruises and shows pretty evenly between taking my Challenger convertible I bought 25 years ago, and taking my Magnum. I had equal enjoyment driving both cars, the fact the Magnum is only worth a fraction of what the convertible is worth has no effect on that, and thinking about what some millionaire paid for a rare car at an auction never crossed my mind while I was driving my cars!
