The 1999 Cadillac Escalade is really more a GMC Yukon Denali than it is a Cadillac. (And GMC's Yukon Denali is really more Yukon than anything else -- except, perhaps, a Chevrolet Tahoe, but that's another story). Regardless of its origins, think of the Escalade as a big four-wheel-drive Cadillac limo for well-heeled outdoorsy types. Loaded with luxury touches and every possible convenience (even GM's OnStar mobile communications system), Escalade comes in four special colors and lacks only one thing: an options list. Why? It's got it all.
