i love this 4x4 ,, i need help for changing the background ,, any ideas guys ?

Since your current background is all white, you could just use the magic wand tool and delete all of it. Then just place a new background behind the car

Dont think he needs help performing the background. (the mods look too good :DDD )
Here's one I found, just browsed jeeps n shizzle. Did a test fit and it should work.
