I recently bought a Frontier XE, mostly for light hauling and commuting. Really nice vehicle for the money. Basically got it for the same price as Colorado, but felt it outclassed the Chevy in ride and engine refinement. Even the base model looks good (unlike the Taco, which looks silly to me with the 4x2 base wheels). A lot of hard plastic inside, but this is PU truck - so what. I've only had the truck for a few hundred miles so I guess you would expect reliabilty to be good.
Overall build quality, looks, ride.
More features on the 4 cyl models. Why do I have to buy a 265hp guzzler to get power windows and locks?
