To estimate the price of the 2012 Kia Cerato Koup I4 1.6L Top with 299900 km mileage, I considered the available data. The closest data point is an offer accepted for a similar car with 255500 km at SAR 19500 on 30 Sep 2024. This car has lower mileage, so the target car's value should be slightly less. A similar car with 255500 km is listed at SAR 19000, which is likely higher than the actual selling price. Another 2014 model with a larger engine and similar mileage is listed at SAR 30000, but this is not directly comparable due to the different engine size and year. Considering the higher mileage of the target car and typical depreciation, the estimated market price should be lower than SAR 19500.
