The car in question is a 2023 BMW 735 TwinPower Turbo i6 3.0L Standard with 18,000 km mileage. We have a listed price for a similar 2024 model with 7,000 km at SAR 420,000. Considering the 2023 model is a year older and has higher mileage, we should expect a lower price. The new car prices for the 2025 BMW 7 Series start at SAR 407,000 for the 730Li, which is a lower variant than the 735. Assuming a 15% depreciation per year, the 2023 model would have depreciated approximately 30% from its new price. Without the exact new price for the 735, we estimate based on the 730Li's price. The 2023 model's price would be lower than the 2024 listed price due to age and mileage, so we adjust accordingly.
