To estimate the price of the 2015 Geely Emgrand 8 I4 2.0L Standard with 208000 km mileage, I considered the following data points: 1) A similar car with 166000 km sold for SAR 9000 on 2023-09-19. 2) Another similar car with 171000 km but a 2.4L engine sold for SAR 20000 on 2023-09-21. 3) A car with the same specs and mileage listed for SAR 18000 but not delisted. 4) A similar car with 229000 km listed for SAR 9500 and delisted on 2023-09-24. 5) A similar car with 166000 km listed for SAR 9000 and delisted on 2023-09-22. Considering the higher mileage of the target car and the average condition, I adjusted the price downwards from the listed prices and closer to the actual selling prices, giving more weight to the SAR 9000 sale and the SAR 9500 listing.
