One thing that I have found to always be the case is that if you need a truck, a real truck is always makes the best truck. Flashbacks of transporting a motorcycle in the back of a Chevy Colorado keep running through my head.
With Pontiac's new Sport Truck, I can't help but look at it and think about how much better the regular G8 looks. That being said, there is a place for this, in my opinion. I just don't feel there is a strong enough market or following for people to really take hold to the idea. It works in Australia, though.
