What is made in Alabama, seats seven, has 536 horsepower, weighs 5,800 pounds and does 0-60 mph in 4.8 seconds? The Mercedes-Benz GL63 AMG, of course! When little Cooper is late for soccer practice and Katilyn late for cheerleading, supermom Debbie can throw them in the GL63 AMG and cruise to an electronically-limited 155 mph to make up time all while hauling a living room set from the Pottery Barn in the rear. This is a monster of a machine that can basically do everything and then some. Does that mean everyone bought them? No. Mercedes said just two percent of GL buyers opted for the GL63 and I’m sure that had a lot to do with the $121,000 price tag. Now that these X166s are a few years old and therefore heavily depreciated, does it make sense to scoop one up? Lets find out.
