Go for garage job? (6)
I believe the answer is:
repair
I believe this clue is a double definition.
'go' is the first definition.
(I've seen this before)
'garage job?' is the second definition.
(I've seen this in another clue)
'for' is the link.
(Other definitions for repair that I've seen before include "Once, return" , "Correct" , "Make one's way (to); fix" , "Withdraw" , "Restore after damage" .)
