Summary

This 2021 executive sedan presents a unique opportunity in the GCC market, combining incredibly low mileage with a highly efficient diesel powertrain that is rare for this segment locally. Having covered just 5,000 kilometers since new, it offers the mechanical freshness of a showroom vehicle while benefiting from the initial depreciation curve. The crisp white exterior is the most sought-after color in the region, ensuring maximum heat reflection during the summer months and maintaining the strongest possible resale value when it comes time to upgrade. While most of its peers in the UAE and Saudi Arabia utilize petrol engines, this six-cylinder diesel unit provides exceptional torque for highway overtaking and unparalleled range between fill-ups. It stands out by offering a level of interior technology and ride quality that few rivals can match, making it an ideal choice for the discerning executive who prioritizes long-distance efficiency and prestige. For a buyer in the GCC, the primary consideration is the Japanese specification, which ensures the vehicle has been maintained to rigorous standards but requires checking local service center compatibility for the diesel engine configuration.

This Car vs Other 2021 S400s

With only 5,000 kilometers on the odometer, this vehicle sits in the lowest percentile of usage for its model year in the GCC market, where active drivers often exceed 20,000 kilometers annually. Most 2021 models found locally have already transitioned into high-utilisation cycles, whereas this example remains in a virtual time-capsule state. The white paintwork is a significant advantage in the Middle Eastern climate, as it significantly reduces cabin heat soak compared to darker alternatives found in the used market. This specific car represents a bridge between the previous generation's legendary reliability and the cutting-edge digital architecture of modern luxury. Choosing a vehicle with such minimal mileage effectively resets the ownership clock for a GCC buyer, offering many years of service before major maintenance milestones are reached. It is a standout choice for those who want the prestige of the latest body style without the immediate depreciation of a brand-new purchase.

STD vs Lower Trims

Even in its standard configuration, this trim level surpasses the flagship offerings of most other brands by including the MBUX Infotainment system as a baseline. GCC buyers will particularly appreciate the inclusion of a high-performance Burmester Surround Sound system and the comprehensive ambient lighting package that transforms the cabin during night drives between emirates. Unlike lower-tier luxury sedans, this car features 360-degree camera systems and parking assistance as standard, which are essential for navigating tight parking structures in Dubai or Riyadh. The ventilated seating and multi-zone climate control are calibrated to handle extreme humidity and heat, providing a level of cooling that is noticeably superior to mid-range executive trims. Furthermore, the inclusion of soft-close doors and a powered trunk adds a layer of convenience that defines the premium ownership experience in this region. This trim ensures that every passenger, not just the driver, enjoys a business-class atmosphere.

S400 vs Segment Rivals

When compared to the BMW 7 Series or the Audi A8, this model leads with its sophisticated air suspension system which provides a 'magic carpet' ride over the expansion joints of the E11 highway. While rivals often transition to smaller four-cylinder engines in their base trims, the 3.0-liter six-cylinder heart of this car maintains the smooth power delivery expected of a flagship luxury vehicle. Its diesel powertrain offers a massive advantage in range, allowing for a round trip between Dubai and Abu Dhabi for several days without needing to visit a fuel station—a convenience neither the 7 Series nor the Lexus LS can easily match. The interior noise insulation is also widely considered the benchmark in this class, keeping the cabin serene even during high-speed desert winds. For the executive who values a quiet, effortless commute, this vehicle provides a more isolated and prestigious environment than any of its immediate European or Japanese competitors.

Running Costs & Resale

The diesel engine provides a significant reduction in monthly fuel expenses, with fuel consumption averaging between 6.0 and 7.5 liters per 100km depending on how much stop-start city traffic is encountered in places like Downtown Dubai. Service intervals typically occur every 15,000 kilometers or once a year, and while this is a Japanese spec car, the abundance of specialist independent garages across the UAE and Saudi Arabia ensures that parts availability remains high despite it being a non-GCC specification. Authorized service centers for this brand are conveniently located in almost every major city across the GCC, from Muscat to Kuwait City. Historically, this model experiences an annual depreciation of approximately 14-16% in the local market, which is more stable than many high-end Italian or British luxury brands. The rare combination of white exterior paint and incredibly low mileage will likely cushion this car against future depreciation, making it a smarter long-term asset than a higher-mileage GCC-spec unit.

Performance & Capability

The 333 horsepower generated by the turbocharged 6-cylinder engine allows for effortless acceleration, reaching 100 km/h in roughly 6 seconds, which is more than sufficient for merging into fast-moving highway traffic. The real strength of this powertrain is the torque available at low RPMs, providing instant response whenever the driver needs to overtake. The rear-wheel-drive configuration ensures a classic driving feel with a tighter turning circle than many smaller cars, making it surprisingly agile in urban environments. Dynamic Select modes allow the driver to stiffen the suspension for more spirited driving on the winding roads of Jebel Jais or soften it for a relaxed cruise. The automatic transmission is tuned for imperceptible shifts, ensuring that power delivery is always linear and never disruptive to the cabin’s tranquility. It is a car designed for composure at high speeds, staying planted and stable even when cruising at the upper limits of UAE highway speed regulations.

Comfort & Cabin

The cabin is a five-seat sanctuary featuring premium leather and meticulous wood or metal trim typical of the highest automotive standards. The air conditioning system is world-class, capable of cooling the interior from 50 degrees to a comfortable 21 degrees in a matter of minutes, a vital feature for anyone living in the Gulf. Rear passengers benefit from generous legroom and dedicated cooling vents, ensuring that those in the back are just as comfortable as those in the front during family road trips. The MBUX system features voice control that can adjust the temperature or change the radio station without the driver taking their eyes off the road. Cabin insulation is enhanced by acoustic glass that filters out the roar of high-speed tires and wind, making it possible to hold a whispered conversation at 120 km/h. This is a car built for the long haul, where the seats are designed to prevent fatigue even after four or five hours of continuous driving.

Safety

This sedan is equipped with an industry-leading suite of safety technologies, including Pre-Safe impulse side protection which can move passengers away from the site of a side impact. For the fast-paced highways of the GCC, the Active Distance Assist Distronic and Steering Assist provide a semi-autonomous driving experience that significantly reduces driver stress. Blind-spot monitoring and lane-keeping assistance are particularly valuable on multi-lane roads where traffic moves at varying speeds. The vehicle also features a 5-Star NCAP safety rating, providing peace of mind for families and professionals alike. Multiple airbags and a rigid passenger cell ensure maximum protection, while the advanced braking system can detect pedestrians or obstacles and apply emergency pressure automatically. These systems are not just electronic gimmicks; they are essential tools for navigating the unique and often unpredictable driving conditions found throughout the region.

The bottom line

This S400 is the perfect match for a buyer who wants a near-new flagship experience with the efficiency of a modern diesel engine. Its exceptionally low mileage and classic white finish make it one of the most compelling value propositions currently available in the UAE for someone moving between luxury and sensible long-term ownership.
