To estimate the price of the 2021 Mitsubishi Attrage V3 1.2L Standard with 270500 km mileage, I first considered the selling prices of similar cars. The 2019 Attrage with 175000 km sold for 22000 SAR in June 2024, and the same model with 155500 km sold for 17000 SAR in August 2024. These cars have lower mileage than the target car, suggesting a lower price for the target. The 2022 Attrage with 41000 km sold for 37000 SAR in March 2024, but it is newer and has much lower mileage. For listed prices, a 2021 Attrage with 129000 km was listed for 29500 SAR in February 2024, but the target car has much higher mileage. Considering the depreciation and higher mileage, the target car's price should be lower than these examples. Based on these data points, I estimate the market price of the target car to be around 15000 SAR.
