Proudly display evidence of accident in fast vehicle (6,3)
I believe the answer is:
sports car
'fast vehicle' is the definition.
(I've seen this before)
'proudly display evidence of accident' is the wordplay.
'proudly display' becomes 'sport' (sport can mean to wear or display).
'evidence of accident' becomes 'scar' (an accident might cause a scar).
'sport'+'scar'='SPORTS-CAR'
'in' is the link.
(Other definitions for sports car that I've seen before include "Racer" , "One often with hood down" , "Soft-top, say" , "flashy motor" , "Low-slung two-seater" .)
