To estimate the price of the 2019 Honda Odyssey J I4 2.4L EX (Base) with 118000 km mileage, I started by looking at the new car prices. The 2025 Honda Odyssey J 2.4 EX starts at SAR 137885. Assuming a 10% depreciation per year, the 2019 model would have depreciated for 6 years. The depreciation factor is 0.9^6, which is approximately 0.531. Applying this to the new car price, the estimated value is around SAR 73200. Next, I considered the listed price of a similar 2018 model with higher mileage (160000 km) listed for SAR 70000. Given the 2019 model has lower mileage and is a year newer, it would be reasonable to estimate a slightly higher price. Combining these data points, I arrived at the final estimate.
