Otherwise, you get everything that makes the Escalade ESV the automotive object of a celebrity's affections.  The length eclipses the basic Escalade by 19.4 inches.  Gas consumption comes out to 13 mpg in the city to 19 mpg on the highway.  Take your pick between 18 and 22 inch wheels, then watch heads turn as you roll by the common folk.  Cargo space with all seats up and intact comes out to 45.8 cubic feet.  This vehicle has power outlets accessible from all three rows.
Your opinion of the 2007 Escalade ESV depends on whether or not you emphasize form over function.  If you do, enjoy the technology, power, style, and extra length.  If you don't, think twice before you buy.  Owners would like more gas mileage and fewer maintenance issues.  In the end, the value you derive really depends on who you need to impress.
