Vehicle collecting editor on way back or one used in transaction? (5-2)
I believe the answer is:
trade-in
'one used in transaction?' is the definition.
(as in a used car exchanged as part of a trade-in)
'vehicle collecting editor on way back' is the wordplay.
'vehicle' becomes 'train'.
'collecting' is an insertion indicator.
'editor' becomes 'ed'.
'on way back' says the letters should be written backwards.
'ed' reversed gives 'de'.
'train' placed around 'de' is 'TRADE-IN'.
'or' is the link.
(Other definitions for trade-in that I've seen before include "Something used in part exchange" , "Trained (anag.)" , "Article used in part payment for another" , "Old item given in part payment for a new one" , "I daren't (anag)" .)
