To estimate the price of the 2021 Kia Cerato I4 1.6L LX (Base) with 274,000 km mileage, I first considered the selling prices of similar cars. A 2021 model with 96,000 km sold for 38,000 SAR in June 2024. Given the higher mileage of the target car, its value should be lower. A 2019 model with 119,000 km sold for 36,500 SAR in November 2023, and a 2022 model with 61,000 km sold for 53,000 SAR in May 2024. The target car's mileage is significantly higher, suggesting a lower price. Listed prices for 2021 models with lower mileage range from 42,000 to 46,500 SAR, but these are not actual selling prices. Considering the high mileage and average condition, I estimate the market price to be lower than the 2021 model sold for 38,000 SAR, adjusting for the mileage difference.
