The G63 is such an oddball, one wonders how it even exists? Take a military truck designed in the 1970's, and shove it full of twin-turbo V8, stiff suspension, and big brakes, why would they? Because they are smart enough to know that Americans are dumb enough to buy TONS of them. Utterly confused, we take the G63 to the canyons to see if it's even a little bit sporting.
