Inspect German car and Ford model (5)
I believe the answer is:
audit
'inspect' is the definition.
(synonyms)
'german car and ford model' is the wordplay.
'german car' becomes 'audi' (I've seen this in another clue).
'and' says to put letters next to each other.
'ford model' becomes 't' (I can't explain this - if you can you should give a lot more credence to this answer).
'audi'+'t'='AUDIT'
Can you help me to learn more?
(Other definitions for audit that I've seen before include "Review firm's accounts, annual check" , "Check of books" , "Examine account" , "Go over" , "Financial review" .)
