To estimate the price of the 2014 Lexus ES250 I4 2.5L Excellence Plus (Mid) with 324000 km mileage, I considered the following data points: 1. A 2016 Lexus ES250 I4 2.5L Excellence Plus (Mid) with 267000 km listed for SAR 77500. Adjusting for the older model year and higher mileage, the price would be significantly lower. 2. A 2014 Lexus ES250 I4 2.5L Excellence Plus (Mid) with 157000 km listed for SAR 67000. Given the higher mileage of the target car, the price would be lower. 3. A 2014 Lexus ES250 I4 2.5L Elegant (Base) with 152000 km listed for SAR 76000. The target car is a higher trim but has much higher mileage, so the price would be lower. Considering these factors, I adjusted the price downwards for the higher mileage and average condition.
