Have owned the Colorado V8 for around 18 months, and it has been a true joy to drive, 300 HP in this relatively light vehicle is amazing, and it is a real sleeper. The sports suspension and low profile tires make it corner flat in most all situations. This is a little like driving a vette in pickup clothing.
On the downside, the interior is pretty spartan, and the ride can get a little rough at times. Gas mileage pretty much sucks. All in all, a fine vehicle that I would buy again.
