To estimate the price of the 2019 Infiniti QX80 V8 5.6L Limited Edition with 215500 km mileage, I first looked at the selling prices of similar cars. A 2021 model with 56300 km sold for 225000 SAR in December 2023, and a 2017 model with 94000 km sold for 115000 SAR in December 2023. Given the significant mileage difference, I adjusted the price downward. Next, I reviewed listed prices: a 2019 model with 176000 km was listed for 173500 SAR, and another 2019 model with 85000 km was listed for 199500 SAR. Considering the higher mileage of the target car, I further adjusted the price downward. Finally, I factored in the condition and depreciation over time to arrive at a fair market estimate.
