To estimate the price of the 2020 Infiniti QX70 V6 3.7L S (Top) with 28000 km mileage, I started by looking at the new car price for a 2025 Infiniti QX70 Standard SUV, which is SAR 219500. Given that the car in question is a 2020 model, I applied a 10% depreciation per year over 4 years, resulting in a depreciation of approximately 34.39%. This brings the estimated value of a new 2020 model to around SAR 144000. Next, I considered the listed prices of similar cars: a 2020 Infiniti QX70 V6 3.7L Standard with 52000 km listed for SAR 93500 and a 2019 model with 150000 km listed for SAR 102000. Given the lower mileage and higher trim of the car in question, I adjusted the price upwards from the 2020 model listed price. Factoring in the better condition and lower mileage, I estimated the market price to be slightly higher than the listed 2020 model.
