To estimate the price of the 2023 BMW 430 xDrive I4 2.0L Twin Power Turbo (M Kit) Standard, I started by looking at the new car prices for similar models. The 2025 BMW 420 Standard Convertible is priced at SAR 311,000, the 2025 BMW 428 Standard Convertible at SAR 325,500, and the 2025 BMW 435 Standard Convertible at SAR 354,500. Since the 430 xDrive is likely positioned between the 428 and 435 models, I estimated its new price to be around SAR 340,000. Given that the car is a 2023 model, it has depreciated for one year. Assuming a 10% annual depreciation, the estimated depreciation amount is SAR 34,000. Subtracting this from the estimated new price, the estimated market price for the used car is SAR 306,000.
