To estimate the price of the 2018 Lexus NX300 I4 2.0L Turbocharged Sport (Top) with 238439 km mileage, I considered the listed prices of similar cars. The 2020 Lexus NX300 I4 2.0L Turbocharged Sport (Top) with 99000 km is listed for SAR 120000. The 2019 Lexus NX300 I4 2.0L Turbocharged Excellence (Mid) with 108000 km is listed for SAR 130000. The 2020 Lexus NX300 I4 2.0L Elegant (Base) with 111000 km is listed for SAR 100500. Given the higher mileage and older model year of the target car, I applied a depreciation factor. The target car's higher mileage and average condition further reduce its value. Considering these factors, I estimated the market price accordingly.
