Grandpa Motor Company. This truck is the truck you most often see in 2 wheel drive. The new Duramaxes are made for old men who like to drive their trucks once a month and never take them offroad. New GMCs dont have a solid front axle making them damn near offroad incapable.

Duramax is a great engine. Isuzu did a good job there. Fuck duramaxes i'll smoke any duramax in my ford 6.0 powerstroke.

GMC Terrain

A mid-size crossover SUV that really pulls some ass. Manufactured by General Motors Company, the Terrain destroys all other vehicles and makes them look silly with its awesome power and beautiful design. Dudes and ladies alike get laid constantly while cruising around in one of these bad boys.

"Just got a new GMC Terrain so it looks like I'm going to pound town tonight!"
