My ds adores his diecast and plastic disney cars with eyes.
There are different body colours of the same models (dinaco blue mcqueen/bug mouth red mqueen/ dirty wheels mcqueen etc) and he spends long periods of time 'sorting' them into piles of the same model and then lining them up all the same direction bumper to bumper along edges of things, like rugs and kitchen worktops
Does anybody else have a cars fanatic?
