A quarrel when you take the new car for a drive (3-2)
I believe the answer is:
run-in
'a quarrel' is the definition.
(I know that quarrel can be written as run-in)
'you take the new car for a drive' is the wordplay.
I cannot quite understand how this works, but
'you' could be 'u' (homophones) and 'u' is present in the answer.
'take' could be 'r' (abbreviation for 'recipe', Latin for 'take') and 'r' is found in the answer.
'new' could be 'n' (abbreviation as in New Testament NT) and 'n' is found within the answer.
The remaining letters 'in' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'when' is the link.
Can you help me to learn more?
(Other definitions for run-in that I've seen before include "Home straight" , "Quarrel" , "Disagreement (with authority?)" , "Matches late in season" , "Fight, disagreement" .)
