Do you think any recently manufactured vehicle will be considered "classic", in the classic sense of classic. The only reason any of the shit produced today will be desirable is that it's better than the shit produced tomorrow. If you can fix it at all, which you won't be able to.
We can't get chips for stuff we made last year, forget completely five years ago. You can't machine chips in your shop, and none of this latest car crap works without chips.
8086 chips first came out in the late 70s and are still made today.
The computer systems in all cars today are well described in publicly available manuals within 3 years of the car coming out.
You just have to know where to look.
Computer driven fuel and transmissions in cars today make the cars much safer to drive and for the right driver, open up all the car's capabilities.
