Examiner's car rubbish reversing (7)
I believe the answer is:
auditor
'examiner's' is the definition.
(an auditor examines accounts etc)
'car rubbish reversing' is the wordplay.
'car' becomes 'audi' (audi is a german car brand).
'rubbish' becomes 'rot' (I've seen this before).
'reversing' is a reversal indicator.
'rot' back-to-front is 'tor'.
'audi'+'tor'='AUDITOR'
(Other definitions for auditor that I've seen before include "Account inspector" , "He'll check the accounts" , "Listener; checker" , "Listener; scrutineer" , "Money expert" .)
