I started by examining the selling prices of similar cars. Two 2013 Chevrolet Sonic I4 1.6L Standard sedans with 155,000 km mileage sold for SAR 13,000 each in early 2024. The car to be estimated is a 2012 model with significantly higher mileage at 295,000 km. Given the one-year age difference and the much higher mileage, the estimated price should be lower. The listed prices for similar cars include a 2012 model with 184,200 km listed at SAR 15,000 and a 2013 model with 155,000 km listed at SAR 13,500. These listed prices are generally higher than selling prices. Considering the high mileage and average condition of the car to be estimated, I adjusted the price downwards from the SAR 13,000 selling price of the 2013 models to account for the additional depreciation due to mileage and age.
