The most relevant data point is the selling price of a 2015 Mercedes S500 V8 4.7L Twin Turbo coupe with 108663 km, which sold for SAR 206325 in August 2024. The car to be estimated is a 2016 model with 120000 km, which is slightly newer but has more mileage. The listed price for a similar 2016 coupe with 93000 km is SAR 275000, but this is likely higher than the market value. Considering the selling price of the 2015 model and adjusting for the year difference and mileage, the estimated price should be slightly higher than the 2015 model's selling price but lower than the listed price. The condition of the car is average, which might slightly lower the price compared to the good condition of the sold 2015 model.
