To estimate the price of the 2020 Geely Coolray I3 1.5L Turbocharged GS (Base) with 65317 km mileage and average condition, I analyzed the provided data points. The most relevant selling prices are: SAR 38500 for a mid-variant with 39450 km (good condition), SAR 39000 for a base variant with 51000 km (average condition), SAR 39000 for a base variant with 41000 km (good condition), SAR 36500 for a base variant with 71000 km (average condition), and SAR 42000 for a base variant with 60000 km (average condition). The listed prices for similar cars range from SAR 39000 to SAR 46500, but these are generally higher than actual selling prices. Considering the car's mileage and condition, I adjusted the price slightly lower than the average selling price of similar cars in average condition.
