The car to be estimated is a 2017 Kia Cerato I4 1.6L LX (Base) with 54,000 km mileage. The most relevant data points are the selling prices of similar cars. A 2017 model with 123,000 km sold for 37,000 SAR on 2024-03-15, and another with 192,975 km sold for 32,000 SAR on 2024-09-03. A 2017 model with 253,950 km sold for 22,500 SAR on 2024-10-15. The car with the closest mileage to the target is the 2017 model with 123,000 km, which sold for 37,000 SAR. Given the target car's lower mileage of 54,000 km, it should be valued higher. Considering depreciation and the condition, an estimate around 40,000 SAR is reasonable.
