To estimate the price of the 2016 Kia Grand Carnival V6 3.3L GDI EX (Mid) with 261000 km mileage, I started by looking at the new car prices for the 2025 model. The closest variant, the 2025 Kia Grand Carnival GDI EX (Mid), is priced at SAR 127500. Assuming a 10% depreciation per year, the car would depreciate approximately 50% over 5 years, bringing the value to around SAR 63750. However, considering the car's age (8 years), higher mileage, and average condition, further depreciation is necessary. I then looked at listed prices of similar 2016 models: the GDI L (Base) variant listed for SAR 31500 and the GDI SXL (Top) variant listed for SAR 47000. Given that the EX (Mid) trim is between these two, and factoring in the higher mileage and average condition, I estimate the market price to be slightly higher than the base variant but lower than the top variant.
