To estimate the price of the 2017 Infiniti Q70 V6 3.7L Luxe Proactive (Top) with 219888 km mileage, I first considered the actual selling price of a similar car with 126000 km mileage sold for SAR 55000 on 2024-08-02. Given the higher mileage of the target car, I adjusted the price downwards. I also reviewed listed prices: SAR 52000 for 179690 km, SAR 65000 for 160000 km, and SAR 55000 for 126000 km. The listed prices are generally higher than selling prices, so I adjusted accordingly. Considering the higher mileage and average condition, I estimated the market price to be lower than the lowest listed price and the actual selling price, accounting for the additional depreciation due to higher mileage.
