On level ground or ...downhill?
Don't know.
There are a couple of vehicles sold in Mexico and elsewhere that I'd
love to have here in the States, but are not legally sold here and can't be licensed for safety, emissions or other (?) reasons. People can, however, get around that a couple of ways. For example, the Suzuki Jimney (an evolution of the old "Samurai") has been brought here as a strictly "off road" vehicle and then you can get a permit to make them "street legal" in some states like Arizona. I drove one briefly in Costa Rica and would love to have one here, but all in all I'm not that much of a car guy to go to all that trouble. Here's a '22 Jimney:

I could similarly imagine somebody trying to bring in an old CV2 for "offroad use" calling it a "Bizarro Baja Bug", like the French "Herbie"!

Getting that 60s-70s vibe?
Apparently another avenue for expats and dual citizens is to take an otherwise non-licensable vehicle that's licensed where they live outside the US (Mexico or Canada) and drive it into the US for up to one year. See below:
Nonresidents may import a vehicle duty-free for personal use up to (1) one year if the vehicle is imported in conjunction with the owner's arrival. Vehicles imported under this provision that do not conform to U.S. safety and emission standards must be exported within one year and may not be sold in the U.S.
