The car to be estimated is a 2023 Lexus ES250 I4 2.5L Excellence Plus (Mid) with 66600 km mileage. The most relevant data point is a similar car with the same variant and specs, sold for SAR 179025 on 2024-05-09, but with only 21000 km mileage. Given the higher mileage of the car to be estimated, its value should be lower. Listed prices for similar cars with lower mileage range from SAR 176000 to SAR 194000, but these are not actual selling prices. Considering the depreciation due to higher mileage and the selling price of a similar car, the estimated market price should be adjusted downward from the SAR 179025 benchmark.
