Unique car returned, albeit damaged (10)
I believe the answer is:
inimitable
'unique' is the definition.
(thesaurus)
'car returned albeit damaged' is the wordplay.
'car' becomes 'mini' (Mini Cooper**).
'returned' says the letters should be written backwards.
'damaged' is an anagram indicator.
'mini' reversed gives 'inim'.
'albeit' with letters rearranged gives 'itable'.
'inim'+'itable'='INIMITABLE'
(Other definitions for inimitable that I've seen before include "Unique" , "not matched by others" , "Matchless" .)
