Carmen, say, with some Mini Cooper accessories (5)
I believe the answer is:
opera
'carmen say' is the definition.
(Carmen is an example)
'some mini cooper accessories' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'OPERA' is hidden within 'mini cooper accessories'.
'with' is the link.
(Other definitions for opera that I've seen before include "Form of theatre" , "Musical entertainment" , "Falstaff, say" , "Patience, for example" , "Musical theatre work" .)
