To estimate the price of the 2019 Lexus ES250 I4 2.5L Elegant (Base) with 142000 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. Given the higher trim and lower mileage, this car would be valued higher than the target car. 2. A 2018 Lexus ES250 I4 2.5L Elegant (Base) with 139000 km is listed for SAR 110000. This car is one year older but has similar mileage and the same trim. 3. A 2020 Lexus ES250 I4 2.5L Elegant (Base) with 110000 km is listed for SAR 131500. This car is one year newer with lower mileage. 4. A 2019 Lexus ES250 I4 2.5L Excellence Plus (Mid) with 182000 km is listed for SAR 111500. This car has higher mileage and a mid trim. 5. A 2019 Lexus ES250 I4 2.5L Excellence Plus (Mid) with 72000 km is listed for SAR 120000. This car has lower mileage and a mid trim. Considering the above data points, the target car's price should be lower than the F-Sport variant but higher than the older 2018 model. The price should be close to the 2018 Elegant (Base) model but adjusted for the one-year difference and slightly higher mileage.
