I saw one being torn down when I was traveling from Abilene one day, many years back. I say torn down, as the owner was scrapping it and not trying to restore it at all. He claimed it was not worth the effort for parts and the cost of them at the time.
They look cool and I have always enjoyed Henry J's and even Morris Minors and the P544 Volvos I have owned in the past. However, I am pretty doubtful as to them meeting safety standards here in the US for any consideration at all of any serious future import possibilities. Probably very little market for them here to begin with and likely no real dealership network going for them. Still, they do look like fun and that is half the drive in any automobile. I still have fond remembrances of all of those small cars, including the Metropolitan and MGB. Heck, even my more modern Geo Metro convertible was fun to have owned.
