To estimate the price of the 2022 Land Rover Defender 110 X I6 3.0L Turbocharged (P400) with 42,000 km mileage, I used the new car price of the same model as a reference. The 2025 Land Rover Defender 110 X (P400) is priced at SAR 456,665. Given that the car is two years old, I applied a 10% depreciation per year. For the first year, the depreciation is 10% of 456,665, which is 45,666.5 SAR. For the second year, the depreciation is 10% of the remaining value (456,665 - 45,666.5), which is 41,099.85 SAR. The total depreciation over two years is 86,766.35 SAR. Subtracting this from the new car price gives an estimated value of 369,898.65 SAR. Considering the car's good condition and mileage, I rounded the estimate to the nearest thousand.
