Although not widely distributed, making it more exclusive, the Mercedes-Benz R-Class remains true to its initial intent, which is to transport up to seven passengers and all their gear with ease. This ultra-comfortable crossover knows how to spoil occupants in the quietest of environments. Both the R350 4MATIC and R350 BlueTEC 4MATIC versions are available. The diesel engine may only deliver 210 hp, but it impresses drivers nonetheless with 400 lbs.-ft. of torque.
