To estimate the price of the 2013 Mercedes ML350 V6 3.5L Standard with 138000 km mileage, I considered the following data points: 1) A 2013 ML350 with 215660 km sold for 67000 SAR on 2023-11-03. 2) A 2014 ML350 with 120000 km sold for 62500 SAR on 2024-01-10. 3) A 2013 ML350 Turbocharged with 229000 km sold for 70000 SAR on 2024-07-20. The selling prices of these cars suggest a range between 62500 and 70000 SAR. Given the lower mileage of the target car (138000 km), it should be valued higher than the 2013 model with 215660 km but lower than the 2013 Turbocharged model. Considering the average condition and the standard variant, I estimate the market price to be around 68000 SAR.
