After party daughter is given something valuable - a vehicle (6)
I believe the answer is:
dodgem
'a vehicle' is the definition.
(Dodgem is an example)
'after party daughter is given something valuable' is the wordplay.
'after' is a charade indicator (letters next to each other).
'party' becomes 'do' (do is a kind of party).
'daughter' becomes 'd'.
'is given' says to put letters next to each other.
'something valuable' becomes 'gem'.
'do' next to 'd' is 'dod'.
'dod'+'gem'='DODGEM'
(Other definitions for dodgem that I've seen before include "Car used in fairground" , "Small car at funfair for bumping into others" , "Bumper car" , "Fairground amusement vehicle" , "ride - with 14a" .)
