Parking skill displays character (4)
I believe the answer is:
part
'character' is the definition.
('part' can be a synonym of 'character')
'parking skill' is the wordplay.
'parking' becomes 'p'.
'skill' becomes 'art' (I've seen this before).
'p'+'art'='PART'
'displays' is the link.
(Other definitions for part that I've seen before include "Sever; portion" , "goodbye" , "Component; divide" , "Portion, segment" , "Member" .)
