Used anchor to display car (5)
I believe the answer is:
sedan
'car' is the definition.
(I know that sedan is a type of car)
'used anchor to display' is the wordplay.
'to display' indicates the answer is hidden within the clue (I've seen 'displays' mean this).
'SEDAN' is hidden within 'used anchor'.
(Other definitions for sedan that I've seen before include "Saloon car in America" , "Dean's in an old conveyance" , "Covered seat carried by bearers" , "Saloon car (US)" , "big chair" .)
