One common piece of misinformation on many of the sites is that only 20 Futuros were ever made. In fact, a total of 48 Futuro houses were made in Finland, and approximately the same amount were manufactured abroad on license. So, there are about 96 Futuros out there somewhere and hopefully they can all be accounted for one way or another.
If anyone has any information on the Futuro I would love to hear from you!!
