Car's time for inspection (5)
I believe the answer is:
audit
'inspection' is the definition.
(thesaurus)
'car's time' is the wordplay.
'car' becomes 'audi' (audi is a german car brand).
'time' becomes 't'.
'audi'+'t'='AUDIT'
'for' is the link.
(Other definitions for audit that I've seen before include "Inspection of the account books" , "vetting of books" , "Official inspection of company accounts" , "Check of books" , "Roman Aquae Sulis" .)
