About This 2020 Mercedes-Benz S-Class S 450

This 2020 Mercedes-Benz S-Class S 450 carries 81,952 miles, which for a well-maintained flagship luxury sedan is well within its prime. The S-Class platform is engineered to go the distance — with proper care, these vehicles routinely deliver 150,000 to 200,000 miles of refined, comfortable driving. The exterior is finished in a commanding Black, giving this sedan the kind of presence that turns heads on the 91 Freeway and in downtown Riverside alike.

2020 Mercedes-Benz S-Class Performance and Engine

Under the long hood of this S 450 sits a 3.0L twin-turbocharged V6 producing 362 horsepower and 369 lb-ft of torque — numbers that deliver effortless highway merging, confident passing power, and a whisper-quiet cruising experience that the S-Class is globally famous for. Paired with Mercedes-Benz's smooth 9-speed automatic transmission and rear-wheel drive, power delivery is seamless and refined.

The twin-turbo setup provides strong low-end torque, meaning you rarely need to floor it to feel the pull. Whether navigating the congestion near the Galleria at Tyler or stretching out on I-15 toward Corona, this engine feels utterly composed. The RWD configuration keeps the driving dynamics sharp and engaging when you want them to be, while the air suspension — standard on S-Class models — absorbs road imperfections with uncanny grace.

Mercedes-Benz S-Class S 450 Features and Interior

The S 450 trim is far from a base model — it's the entry point into a cabin that most cars can only dream of matching. Expect the full suite of S-Class luxury appointments including a panoramic sunroof, heated and ventilated front seats, a Burmester surround sound system, dual 12.3-inch displays forming the widescreen cockpit, ambient lighting with 64 color options, and Mercedes-Benz's intuitive COMAND infotainment system.

Rear passengers enjoy airline-style legroom, and the cabin is treated with real wood trim, soft-close doors, and attention to detail that simply isn't found at this price point in any other vehicle. Safety technology includes active lane keeping assist, adaptive cruise control, automatic emergency braking, and a 360-degree camera system — features that were cutting-edge even when this car was new.

Mercedes-Benz S-Class Reliability and Ownership

The 2020 S-Class generation benefits from years of refinement. The 3.0L biturbo V6 is widely considered more reliable than the V8 options in the lineup, with fewer complexity-related issues and lower maintenance costs relative to its output. Mercedes-Benz introduced significant improvements to infotainment stability and electrical systems in this generation, addressing many of the concerns owners had with earlier models.

Owners of this generation consistently praise the ride quality, long-distance comfort, and technology integration. Like any European luxury vehicle, scheduled maintenance matters — using genuine Mercedes-Benz service intervals for oil changes, spark plugs, and transmission fluid will keep this car performing at its best for years to come. At this price, the cost-per-feature ratio is virtually unbeatable in the used luxury market.
