Mercedes-Benz GL450 Review

As I fired up the GL450, I noticed that the big Merc's trip computer had begun calculating my mpg. I watched in startled fascination as the idling SUV's fuel economy began to drop from the previous night's calculation. Although Mercedes deserves props (or brickbats) for releasing such a glorious gas hog at the tail end of America's SUV craze, the dropping digits left me wondering how the GL450 could possibly rationalize this lampshade-on-the-head consumptive behavior. Even if the target market's interest in fuel economy is more political than wallet-driven, the GL still needs to stump-up some serious self-justification.
