Dealer held new car after ordering (8)
I believe the answer is:
chandler
'dealer' is the definition.
(thesaurus)
'held new car after ordering' is the wordplay.
'new' becomes 'n'.
'after' is a charade indicator (letters next to each other).
'ordering' indicates anagramming the letters.
'held'+'n'+'car'='heldncar'
'heldncar' is an anagram of 'CHANDLER'.
(Other definitions for chandler that I've seen before include "Candlemaker" , "Supplier of ships' equipment" , "supplying the goods in marine setting?" , "Mystery writer" , "Raymond ......, creator of private eye Philip Marlowe" .)
