The Mercedes-Benz GL-Class is an enormous seven-seat luxury 4x4 produced by the German carmaker. It was first introduced in 2006, and a second-generation version came along in 2013. In 2015, it was renamed as the GLS, and remained on sale until 2020 when it was replaced by a new GLS. Direct rivals of the day were in short supply given the huge size and price of the GL, but buyers might also have considered an Audi Q7, Land Rover Discovery or a Toyota Land Cruiser V8. The big Merc was spacious and luxurious on the inside, and packed with luxury features, but it was expensive to run and its sheer size made it cumbersome to drive in town.
