Saying that, I do not see the Aygo as a true Toyota either, as realistically is part of the Toyota Peugeot Citroën Automobile Czech group.
It's still pretty much a Toyota, the floorpan was designed by Toyota, the running gear is Toyota, and the factory they are built in uses Toyota based standards, of course it is partly run with PSA, only difference really is cosmetics.
I really like the iQ, but between that and the Aygo, I'd go for the Aygo, better value, looks better IMO, slightly bigger and they are good fun around town. To me they are sort of like the modern day 'peoples car', but unfortunately for most by todays standards they are probably too 'basic'.
