 I am about to hit 100k miles today (XE V6, 4WD, Crew Cab, 5 speed).  Haven't had a problem yet and I've worked it hard.  There aren't even any rattles in the interior. It'll tow an 18' boat, haul a yard of stone, plow snow, and commute to work. The ride, handling, and build quality are much better than my previous truck, a Toyota Tacoma. As far as mileage, I have seen 21mpg when driving with a light touch on the highway, but it's mostly 18-20mpg. It's certaintly no worse than any other compact pickup on the market.  I did install a Magnaflow exhaust and K&N filtercharger, which helped with throttle response. Overall, I couldn't really ask for more from a truck.
