To estimate the price of the 2016 Mercedes S500 V8 4.7L Twin Turbo coupe with 93000 km mileage, I first looked at the selling price of a similar car: a 2015 Mercedes S500 V8 4.7L Twin Turbo coupe with 108663 km mileage, which sold for SAR 206325 on 2024-08-20. Given that the car in question is a year newer and has lower mileage, it should be valued slightly higher. Next, I reviewed the listed prices of similar cars. The closest match is a 2015 Mercedes S500 V8 4.7L Twin Turbo coupe with 108663 km listed for SAR 220000, which was delisted on 2024-08-21. Another relevant listing is a 2016 Mercedes S500 V8 4.7L Twin Turbo sedan with 103000 km listed for SAR 220500, delisted on 2023-10-24. Considering the car in question is a coupe, which generally has a higher value than a sedan, and has lower mileage, I adjusted the price accordingly. Factoring in the actual selling price, the listed prices, and the condition and mileage of the car, I arrived at the final estimate.
