Not all vehicles will be down. Diesel and pre-fuel injection vehicles (1984 and earlier) have a MUCH better chance at working because they don’t have electronic chips controlling fuel intake to the engine, they have a mechanical carburator. Throttle Body Injection setups may have electronics that can fry but straight carbs won’t. Worst case maybe the starter or electronic ignition or distributor may need replacign but that is a hell of a lot easier than finding computer chip modules that will work - remember you won’t be able to get them transported to you.
so my ‘89 wrangler might work? sweet. put the top down and cruise in the traffic free streets of NYC. shotgun in hand, of course.
Ironically, NASCAR calls their current generation of “stock” race cars “Cars of Tomorrow”. They have carburetors, pushrod valves, and all the high technology of the 50s. Maybe “cars of yesterday” are what we ought to be buying.
