Clue: At least four edible fruit unfit for family (3-6)
Answer: TWO-SEATER
Explanation: At least four edible fruit unfit for family (3-6)
A charade of TWOS (if you have more than one two, then you have 'at least four') plus EATER ('edible fruit'). The allusive definition refers to a car, say. In my opinion, not the happiest of clues, as all the parts seem a little dodgy.
