Examination of car taking little time (5)
I believe the answer is:
audit
'examination' is the definition.
(I know that audit is a type of examination)
'car taking little time' is the wordplay.
'car' becomes 'audi' (Audi is a German car brand).
'taking' is a charade indicator (letters next to each other).
'little time' becomes 't' (abbreviation for time).
'audi'+'t'='AUDIT'
'of' acts as a link.
(Other definitions for audit that I've seen before include "Financial inspection" , "Financial check" , "Investigate" , "Inspection of records" , "Verify accounts" .)
