With a 62-percent share of the market in its back pocket, GM obviously knows how to build and sell large SUVs. It may be true that gas prices are rising and plenty of people are at least considering smaller cars, but the fact remains that neither Americans nor their families are getting any smaller, which will continue to fuel the demand for spacious, powerful SUVs. For those folks, or anyone who requires an impressive towing capacity or commanding view of the road, the 2007 GMC Yukon (or Chevy Tahoe or Cadillac Escalade) fits the bill perfectly. Plus, GMC has added features like a power tumble-and-fold second-row seat for easier third-row access and a power liftgate with controls on the door, the overhead console, and the key fob.
