To estimate the price of the 2018 Lexus LS500H V6 3.5L (Hybrid) Hybrid Plus (Top) with 107000 km mileage, I considered the listed prices of similar cars. The 2019 model with 127000 km is listed for SAR 204000, the 2020 model with 77500 km is listed for SAR 245000, and another 2018 model with 46000 km is listed for SAR 240000. Given that the car in question has higher mileage than the 2018 model listed for SAR 240000 but lower than the 2019 model listed for SAR 204000, I adjusted the price accordingly. Considering the depreciation and the mileage difference, I estimated the market price to be slightly lower than the 2019 model's listed price.
