To estimate the price of the 2016 Toyota Prius I4 1.8L Hybrid Premium (Top) with 249500 km mileage, I started by looking at the new car prices. The 2025 Toyota Prius Premium (Top) Sedan is priced at SAR 99000. Assuming a 10% depreciation per year, the value of a 2016 model would be approximately SAR 38742. Next, I considered the listed price of a similar 2016 Toyota Prius Premium (Top) with 193000 km, which is SAR 37000. Given the higher mileage of the car in question (249500 km), I adjusted the price downwards to account for the additional wear and tear. Combining these data points, I arrived at a final estimate.
