The Chevrolet TrailBlazer hasn't seen a full redesign for many years, to the point that, from the outside, it now almost looks like a retro-styled vehicle from the SUV glory days of the early-to-mid 1990s. Rest assured, the TrailBlazer has undergone a number of minor updates through the years. Built on a frame typical of pickups and older SUVs, the 2009 TrailBlazer is good for towing and hauling. The mid-size SUV shares its platform with the Buick Rainier and GMC Envoy.
