To estimate the price of the 2015 Lincoln MKC I4 2.3L Ecoboost Reserve Full Option (Top) with 42210 km mileage, I considered the following data points: 1) A similar car with the same variant and higher mileage (67000 km) sold for SAR 55000 on 2024-03-19. 2) Another similar car with the same variant and mileage (42210 km) is listed for SAR 60000 but not delisted, indicating it might be overpriced. 3) Other variants with different engine sizes and higher mileages sold for lower prices, such as SAR 35000 and SAR 31700 for the 2.0L Turbocharged variant with 64169 km mileage. Given the lower mileage and good condition of the target car, I adjusted the price upwards from the SAR 55000 selling price of the similar car with higher mileage.
