To estimate the price of the 2020 BMW 730 Li I4 2.0L Twin Power Turbo with 70000 km mileage, I first considered the selling price of a similar car with 40000 km mileage sold for SAR 123500 in June 2024. Given the higher mileage of the target car, I adjusted the price downwards. Next, I reviewed listed prices of similar cars with mileages ranging from 64000 to 91000 km, with prices between SAR 183500 and SAR 227000. The closest match in mileage (70000 km) was listed for SAR 207000. Considering the actual selling price and the listed prices, I estimated the market price by balancing these figures, giving more weight to the actual selling price and adjusting for mileage and condition.
