Vehicle to display damage (6,3)
I believe the answer is:
sports car
'vehicle' is the definition.
(sports car is a kind of vehicle)
'display damage' is the wordplay.
'display' becomes 'sport' (to sport an item is to wear or display it).
'damage' becomes 'scar' (I've seen this before).
'sport'+'scar'='SPORTS-CAR'
'to' acts as a link.
(Other definitions for sports car that I've seen before include "Soft-top, say" , "flashy motor" , "Lotus perhaps" , "Low-slung two-seater" , "Lamborghini?" .)
