Drake's outside drawn into coach deal (5-2)
I believe the answer is:
trade-in
'deal' is the definition.
(thesaurus)
'drake's outside drawn into coach' is the wordplay.
I cannot really see how this works, but
'into' could be 'in' and 'in' is found in the answer.
The remaining letters 'trade' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for trade-in that I've seen before include "Trained (anag.)" , "Article used in part payment for another" , "Article used in part-exchange" , "Part-exchanged item" , "Something used in part exchange" .)
