To estimate the price of the 2015 Geely Emgrand X7 I4 2.4L GT (Base), I first looked at the selling price of a similar car: a 2016 Geely Emgrand X7 I4 2.4L GS (Top) with 235000 km sold for SAR 15250 on 2024-05-15. This car is a year newer and a higher trim, so the target car should be slightly lower in value. Next, I considered the listed prices of similar cars. The closest match is a 2015 Geely Emgrand X7 I4 2.4L GT (Base) with the same mileage listed for SAR 18000. Other listings include a 2015 model with lower mileage (98488 km) listed for SAR 23000, and a 2014 model with similar mileage (145000 km) listed for SAR 16500. Given the selling price and the listed prices, I adjusted for the target car's average condition and mileage to arrive at a fair market estimate.
