There is no data provided for selling prices, offers accepted, listed prices, or ad prices of similar cars. Additionally, there is no information on the price of new Saudi-spec cars for different variants. Given the lack of specific data, I will use a general depreciation logic. Assuming a new car price of around 100,000 SAR for a 2014 Mitsubishi Montero Sport V6 3.5L GLX, and applying a 10% depreciation per year over 10 years, the estimated value would be around 34,867 SAR. Considering the high mileage and average condition, I will further reduce the estimate by 20%, resulting in a final estimate.
