Why it stands out

The 2014 Mercedes-Benz S-Class stands out as a full-size luxury sedan that pairs serious engineering with unmistakable opulence. For this generation, Mercedes introduced a new aluminum hybrid body shell that cut weight and improved rigidity, and the car also used a surround-view camera system that integrated multi-modal radar and ultrasonic sensors for smoother adaptive cruise control and lane centering. Its cabin was a major part of the appeal, with wood and metal accents, selectable ambient lighting, and a pair of 12.3-inch screens under a single panel that still looked contemporary years later.

What makes the 2014 model especially distinctive is how much advanced technology Mercedes packed into it while still preserving a traditional luxury-car feel. The car retained many physical controls, which may make the interface easier to live with than newer systems, and night vision was still included. It also offered a wide range of luxury and convenience features, including rear executive seating packages, sport packages, AMG appearance packages, air purifiers, active parking assist, massaging seats, and Burmester surround-sound audio. The initial U.S. models were the S 550 and AMG S 63, with the S 550 using a 4.7-liter twin-turbo V8 making 449 horsepower and 516 pound-feet of torque, while the AMG S 63 used a hand-built 5.5-liter twin-turbo V8 making 577 horsepower and 664 pound-feet.

As a used luxury buy, the 2014 Mercedes-Benz S-Class is appealing because it delivers flagship comfort, strong performance, and a long list of high-end features. It is also a complex car, and the source notes that many of its best features were optional, so equipment can vary a lot from one example to another. Even so, owners praise its elegance, workmanship, comfort, and reliability, though it remains expensive compared with newer models and costly to maintain.
