To estimate the price of the 2018 Lexus ES250 I4 2.5L Elegant (Base) with 260000 km mileage, I considered the following data points: 1. A 2019 Lexus ES250 I4 2.5L F-Sport (Top) with 62000 km sold for SAR 150000 on 2024-07-30. This car is a higher trim and in better condition, so it would be priced higher. 2. A similar 2018 Lexus ES250 I4 2.5L Elegant (Base) with the same mileage is listed for SAR 63000. 3. Other listings include a 2017 model with 258000 km listed for SAR 76000, a 2016 model with 267000 km listed for SAR 77500, and a 2018 model with 306000 km listed for SAR 79000. These listings suggest a price range for older models with high mileage. 4. Considering the condition and mileage of the target car, the price should be lower than the listed price of SAR 63000 but higher than the older models. Therefore, I estimate the market price to be around SAR 60000.
