The Mercedes G-Class has been around for 40-odd years now, and while it was once a rugged working vehicle, it’s now marketed as an ultra-fashionable luxury off-roader. On that score, it competes with the likes of the Porsche Cayenne and the Range Rover.
The A-Class is Mercedes' smallest car, a premium hatchback that competes against cars like the BMW 1 Series and the Audi A3.
The in-your-face Mercedes-Benz G-Glass is kind of in a class of one, although you might also consider the Bentley Bentayga and Range Rover.
The CLS is a luxury saloon that’s trying to be a coupe, with four doors but rakish styling. It’s a direct rival for Audi’s A7 Sportback.
