To estimate the price of the 2015 Mercedes ML400 V6 3.0L Twin Turbo Standard with 125835 km mileage and average condition, I analyzed the selling prices of similar cars. The most relevant data point is a car with 199000 km mileage and average condition sold for 70000 SAR on 2024-05-08. Another car with 215000 km mileage and average condition sold for 77000 SAR on 2024-02-17. A car with 250000 km mileage and average condition sold for 60000 SAR on 2024-09-08. Considering the target car's lower mileage and average condition, its value should be slightly higher than the 70000 SAR car but lower than the 77000 SAR car. The listed price of a similar car with 124500 km mileage was 85000 SAR, but listed prices are typically higher than selling prices. Therefore, I estimate the market price to be around 75000 SAR.
