To estimate the price of the 2023 Mitsubishi Xpander I4 1.5L Standard with 42000 km mileage, I first looked at the selling prices of similar cars. A 2021 model with 155000 km sold for 46000 SAR in November 2023, and another 2021 model with 27000 km sold for 51500 SAR in December 2023. Given the mileage and year differences, these prices suggest a range for older models. Next, I considered the listed prices of similar 2023 models: one with 42000 km listed for 66000 SAR, another with 41000 km listed for 61500 SAR, and another with 17000 km listed for 71500 SAR. These listings are higher than the selling prices, indicating a negotiation margin. The new 2024 model price is 79350 SAR, which helps to understand the depreciation. Considering the car's condition is not specified as good, I adjusted the price slightly lower than the average of the listed prices.
