Front of a vehicle? (3)
I believe the answer is:
van
I believe this clue is a double definition.
'front' is the first definition.
(I've seen this in other clues)
'a vehicle?' is the second definition.
(van is a kind of vehicle)
'of' is the link.
(Other definitions for van that I've seen before include "Commercial vehicle or front of army" , "Business vehicles or army front" , "Covered wagon" , "Goods vehicle" , ". . . Morrisson (singer)" .)
