I've been brushing up my knowledge, and you may have seen the biggest collection in one place, Gary! Only 60 went to the USA the first time around, although I bet there are a few more there now. 351 'regular production cars' were made, and by Yamaha not Toyota, spread around the world, and they cost more than a Jag or a Porsche when new.
