To estimate the price of the 2016 Geely Emgrand X7 I4 1.6L GT (Base) with 149000 km mileage, I first considered the selling price of a similar 2016 Geely Emgrand X7 I4 2.4L GS (Top) with 235000 km mileage, which sold for SAR 15250 on 2024-05-15. Given that the target car has a smaller engine (1.6L vs. 2.4L) and is a base variant, it would typically be valued lower. Next, I looked at listed prices: a 2016 Geely Emgrand X7 I4 2.4L GS (Top) with 105000 km was listed for SAR 19000, and another with 102000 km was listed for SAR 23000. These listings are higher than the selling price, indicating that actual selling prices are lower. Considering the mileage and condition, I adjusted the price downwards. The 2014 and 2015 models listed for SAR 16500 and SAR 18000 respectively, also suggest a lower price for older models. Factoring in the smaller engine size, base variant, and average condition, I estimated the market price accordingly.
