Parking vehicle gives sense of achievement (5)
I believe the answer is:
pride
'sense of achievement' is the definition.
'parking vehicle' is the wordplay.
'parking' becomes 'p'.
'vehicle' becomes 'ride'.
'p'+'ride'='PRIDE'
'gives' is the link.
(Other definitions for pride that I've seen before include "conceit" , "Hubris" , "big cats" , "Deadly sin (of lions?)" , "They say it comes before a fall" .)
