Mercedes-Benz recently crowned its S-Class lineup up with the flagship 2015 S 550 Coupe. With a starting price of $147,000, this techno-laden sybaritic slice of personal magnificence might seem a bit dear, but after spending time within its gorgeous confines and behind the silken 449 hp, 516 lb-ft 4.7L twin-turbo V8, this 2+2 comes across as somewhat of a value proposition. That’s if you make a habit of kicking tires in Bentley or Maserati showrooms.
