According to a friend of mine who's a Chevy salesman, he believes the Trailblazer will continue because it can tow. People buy them because they're a lot cheaper than a Tahoe and they can tow their boat, trailer, etc. As I understand it, the Lambda's don't have much of a tow rating. If the Trailblazer goes away, a Chevy buyer would have to go with a Tahoe or a pickup.
