To estimate the price of the 2019 Lexus GS300 I4 2.0L Turbo Charged Standard with 43000 km mileage, I started with the new car price of the 2025 model, which is SAR 324500. Assuming a 10% depreciation per year, the car would depreciate approximately 50% over 5 years, bringing the estimated value to around SAR 162250. Additionally, a similar 2019 model with 42000 km is listed for SAR 144500. Considering the listed price is generally higher than the actual selling price, I adjusted the estimate slightly lower. Given the average condition of the car, I factored in a minor reduction in value as well.
