Free car use given to cupholder (6)
I believe the answer is:
saucer
'cupholder' is the definition.
(I've seen this before)
'free car use given' is the wordplay.
'free' indicates an anagram.
'given' is a charade indicator (letters next to each other).
'car'+'use'='caruse'
'caruse' is an anagram of 'SAUCER'.
'to' acts as a link.
(Other definitions for saucer that I've seen before include "Piece of tableware, goes with cup" , "Shallow dish, flying?" , "Cup holder" , "Cup's partner?" , "See 1" .)
