To estimate the price of the 2019 Geely Emgrand X7 Sport I4 2.4L GS (Top) with 8700 km mileage, I started by looking at the new car prices. The 2024 Geely Emgrand X7 GS (Top) is priced at SAR 79000. Applying a 10% annual depreciation over 5 years (2019 to 2024), the estimated value would be around SAR 47405. However, I also considered the listed prices of similar cars. A 2019 Geely Emgrand X7 Sport I4 2.4L GS (Top) with the same mileage is listed for SAR 56500. Given that listed prices are generally higher than selling prices, I adjusted this downwards. Additionally, a 2020 Geely Emgrand X7 I4 2.4L GT (Base) with 72000 km is listed for SAR 40000, which is a lower trim and higher mileage. Balancing these data points, I estimated the market price accordingly.
