To estimate the price of the 2017 Lexus ES350 V6 3.5L Exclusive (Top+), I first looked at the selling prices of similar cars. The closest match is a 2017 Lexus ES350 V6 3.5L Exclusive (Top+) with 148000 km sold for SAR 100000 on 2023-08-19. Given the higher mileage of 278000 km for the car in question, I adjusted the price downwards. I also considered a 2015 model with 97000 km sold for SAR 70000 on 2024-06-21, which suggests a significant depreciation for higher mileage. Additionally, I reviewed listed prices: a 2017 model with 278000 km listed for SAR 112000, and other 2017 models with lower mileage listed between SAR 80000 and SAR 110000. Considering the higher mileage and the condition, I estimated the price to be lower than the listed price but slightly above the lowest selling price due to the Exclusive (Top+) trim.
