About This 2018 Mercedes-Benz S-Class S 450

At 122,428 miles, this S 450 has been well-traveled — but that's exactly where the Mercedes-Benz S-Class earns its legendary reputation. These vehicles are engineered to last well beyond 200,000 miles when properly maintained, and the S-Class ownership community routinely reports smooth, reliable driving deep into high-mileage territory. For buyers in the greater Los Angeles area looking for flagship-level luxury without the flagship-level new-car price tag, this is a compelling opportunity. The S 450 trim sits as a sweet spot in the S-Class lineup — offering the full luxury experience without the complexity of the larger V8 or V12 variants.
 

2018 Mercedes-Benz S-Class Performance and Engine

Under the long sculpted hood of this S 450 lives a 3.0-liter twin-turbocharged V6 engine — a powertrain that delivers a remarkably satisfying balance of performance and refinement. This engine produces around 362 horsepower and 369 lb-ft of torque, figures that give the S-Class effortless highway merging, confident passing power, and the kind of smooth, linear acceleration that luxury buyers expect.

Power is routed through Mercedes-Benz's excellent 9-speed 9G-TRONIC automatic transmission, one of the smoothest-shifting gearboxes in the industry. Paired with rear-wheel drive, the S 450 delivers a driving dynamic that feels both composed and engaging — a rare combination in a vehicle this large and this comfortable. Whether you're cruising the 110 Freeway through Downtown LA or gliding along Pacific Coast Highway, this powertrain never feels hurried or stressed.
 

Mercedes-Benz S-Class Features and Interior

A Cabin Built Around Passenger Experience

Step inside the 2018 S 450 and you're immediately reminded why the S-Class has set the global standard for luxury interiors for decades. The cabin is a showcase of hand-finished materials, ambient lighting, and technology that was genuinely ahead of its time in 2018 and still impresses today.
 

Technology and Comfort Highlights

The 2018 S-Class S 450 comes loaded with features including dual 12.3-inch widescreen displays forming the COMAND infotainment system, a premium Burmester surround sound system, heated and ventilated front seats, massaging seat functions, a panoramic sunroof, and Mercedes-Benz's signature AIRMATIC air suspension system that delivers a cloud-like ride quality regardless of road conditions. Driver assistance features include active lane keeping assist, blind spot monitoring, adaptive cruise control with stop-and-go functionality, and automatic emergency braking — a suite that was cutting-edge for the era and remains highly capable today.
 

Mercedes-Benz S-Class Reliability and Ownership

The Mercedes-Benz S-Class has a well-earned reputation for long-term durability when maintenance is kept current. The 3.0-liter biturbo V6 in the S 450 is widely considered one of the more dependable engines in the modern Mercedes lineup — less complex than the larger AMG powerplants and generally less prone to the costly issues sometimes associated with the V8 variants. Owners consistently praise the smooth transmission, the air suspension's ride quality, and the overall sense that nothing feels cheap or fragile.

Prospective buyers should budget for Mercedes-Benz-level maintenance costs — oil changes, air suspension components, and brake service carry premium pricing compared to mainstream brands. That said, a well-documented service history and a pre-purchase inspection from an independent Mercedes-Benz specialist can give buyers strong confidence in a high-mileage S-Class like this one. Many S-Class owners report that the 100,000–150,000-mile window is simply a transition into a very affordable luxury ownership experience — the depreciation has already occurred, and the car still drives like a flagship.
