Versatile vehicle (4)
I believe the answer is:
jeep
'versatile vehicle' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for jeep that I've seen before include "Four-wheel-drive general purpose vehicle" , "Army vehicle, 4-wheel drive" , "US army car" , "4WD vehicle" , "Vehicle for rough terrain" .)
