A Gmc TopKick you wont want to be stuck in front of!
Put it this way, if i saw this in my rear-view I would be speeding up or getting the hell out of the way!
From the background posters and the custom decal on the rear i'm guessing this has something to do with the Transformers movie, although I dont think this motor would have to tranform to do any damage at all. With the "road armour" at the front, massive tyres and a ground clearance you could lie under, this is a tank in all but name. The is a prime example of GMC custom work kitted out for Hollywood, I just wish the movies were as good!
