The car to be estimated is a 2015 Mercedes S500 AMG Twin Turbo V8 4.7L Top sedan with 190,000 km mileage. The closest data point is a 2015 Mercedes S500 Twin Turbo V8 4.7L Top sedan with 185,000 km listed for SAR 135,000, delisted in July 2024. This is a strong reference as it matches the variant and body type. A 2014 Top variant with 181,000 km was listed for SAR 150,000, suggesting a slightly higher value for the 2015 model. The selling price of a 2015 Standard variant coupe with 108,663 km was SAR 206,325, but this is less relevant due to the different body type and lower mileage. Considering the Top variant's premium and the higher mileage of the target car, the estimated market price is adjusted slightly below the SAR 135,000 listing to account for depreciation and market conditions.
