I analyzed the selling prices of similar 2016 Mercedes S400 V6 3.0L Twin Turbo cars. The most relevant data point is a car with 115,000 km sold for 164,000 SAR in April 2024. Another similar car with 133,000 km sold for 164,500 SAR in March 2024. A 2017 model with 94,000 km sold for 108,000 SAR in February 2024, but it was in average condition. A 2014 model with 90,000 km sold for 82,000 SAR in February 2024. A 2015 model with 160,000 km sold for 169,000 SAR in June 2023. The car to be estimated has 73,406 km, which is lower than all these cars, suggesting a higher value. The listed prices for similar cars range from 150,000 to 215,500 SAR, but these are not actual selling prices. Considering the lower mileage and good condition, I estimate the price to be slightly higher than the 164,000 SAR sold price for the 115,000 km car.
