To estimate the price of the 2017 Mercedes S400 V6 3.0L Twin Turbo with 165600 km mileage, I first considered the selling prices of similar cars. A 2017 model with 94000 km sold for 108000 SAR in February 2024, but it was in average condition. A 2016 model with 133000 km sold for 164500 SAR in March 2024. Another 2016 model with 115000 km sold for 164000 SAR in April 2024. A 2015 model with 160000 km sold for 169000 SAR in June 2023. The 2017 model's higher mileage and good condition suggest a lower price than the 2016 models with lower mileage. The listed prices for 2017 models range from 145000 to 225000 SAR, but these are often higher than actual selling prices. Considering the depreciation and the condition, I estimate the market price to be slightly lower than the 2016 models' selling prices, around 150000 SAR.
