To estimate the price of the 2019 Infiniti Q70 V6 3.7L Luxe Proactive (Top) with 61000 km mileage, I first considered the selling price of a similar car with 94000 km mileage sold for SAR 83000 on 2023-09-21. Given the lower mileage of the target car, it should be valued higher. The accepted offer for a similar car with the same mileage was SAR 88000 on 2023-09-20, which also supports a higher valuation. The listed price of a similar car with the same mileage is SAR 113500, but listed prices are generally higher than actual selling prices. Considering these data points, I adjusted the price upwards from the SAR 83000 selling price, factoring in the lower mileage and the accepted offer, but kept it below the listed price to reflect a realistic market value.
