!! The GLS 63 AMG is the range topping performance model for the GLS line. With a new MSRP over $130k it almost has every available option you can get on lesser GLS models. The GLS is Mercedes answer to its customers wanting a full-size SUV with third row seating and the ability to tow with a rating up to 7500 pounds when properly equipped. With a twin turbo V8 making over 577-hp this GL 63 is capable of rocketing to 60-mph in under five seconds. An auto leveling air suspension gives this Benz an amazing ride. With meaty tires and a performance suspension and gigantic brakes, this 6,000 pound beast can put a lot of sports cars to shame, yet it has room for the whole family!
