The Mercedes-Benz GL-Class GL450 is a mid-range trim level available during the first two generations of the GL-Class large luxury SUV. The GL-Class, with seating for seven passengers, was introduced in 2006, was redesigned for the 2013 model year, and was phased out after 2016 and replaced with the GLS-Class. With a decade’s worth of GL-Class GL450s on the market, shoppers have a range of options, though it’s worth leaning toward later model years for a safer and more upscale experience. Competitors include the Audi Q7 and the Porsche Cayenne.
