Grand Cherokee maker
I believe the answer is:
jeep
'grand cherokee maker' 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 "Military four-wheel-drive vehicle" , "Four-wheel-drive general purpose vehicle" , "Small four-wheel drive vehicle" , "Army vehicle, 4-wheel drive" , "US army car" .)
