The exterior dimensions for a Mercedes-Benz S 450 L commonly sold in the UAE as a GCC-spec vehicle are approximately 5,320 mm in length, 1,921 mm in width, and 1,503 mm in height, with a wheelbase of 3,216 mm. In the local market, this places it at the top end of the luxury sedan segment, competing directly with the long-wheelbase BMW 7 Series and the Audi A8 L. A practical concern for many owners, especially considering parking in tighter spaces in older areas of Dubai or Sharjah, is its length. While garages in newer villas and most commercial buildings accommodate it, it can be challenging in some older parking structures designed for smaller vehicles. The combination of its size and the standard air suspension ensures a uniquely smooth ride on long highway stretches like the Dubai-Abu Dhabi E11 road, even at higher speeds. The RTA Dubai's vehicle registration database and showroom specifications from local dealers, which often highlight the increased rear legroom as a key selling point, confirm these dimensions as standard for current GCC models. From a total cost of ownership perspective in the Emirates, its size impacts several factors: annual insurance premiums from companies like Oman Insurance or AXA can be 5-10% higher than for a standard E-Class, fuel consumption with Special 95 premium gasoline typically ranges between 7.2 to 8.5 km/l in mixed city-highway driving common to the UAE, and annual depreciation based on data from Dubizzle listings for 2020-2022 models is approximately 15-18% for the first three years, translating to an annual loss of around 70,000 - 85,000 AED for a new vehicle.
