To estimate the price of the 2019 Infiniti QX50 I4 2.0L Turbocharged Autograph (AWD) (Top) with 70555 km mileage, I considered the listed prices of similar cars. The closest match is a 2019 model with 66000 km listed for SAR 103000. Another 2019 model with 91000 km is listed for SAR 77500, and a 2020 model with 99000 km is listed for SAR 92500. The 2021 models with lower mileage (42000 km and 35000 km) are listed for SAR 123500 and SAR 114500 respectively. Given the average condition of the target car and its mileage, I estimated the price to be slightly lower than the 66000 km car but higher than the 91000 km car. Therefore, I arrived at an estimated price by averaging these values and adjusting for mileage and condition.
