The first truck to bear Cadillac's crest is big, roomy and comfortable. The Escalade is Cadillac's answer to the Lincoln Navigator. The Cadillac Escalade is nearly identical to the Chevrolet Tahoe, GMC Yukon and Yukon Denali. What an Escalade buyer gets for Cadillac cash is a load of standard features, fancy wood trim and slightly less interior noise. The Escalade comes with the full service of a Cadillac dealership, which in some locations means demo cars delivered to a potential customer's door. Escalade's no-options price includes Cadillac's OnStar communications system. Used to its full extent, OnStar is a real benefit. The value of red-carpet treatment and Cadillac luxury shouldn't be minimized. Since the launch in the fall of 1998, Cadillac has been selling Escalades as fast as it can build them.
