To estimate the price of the 2018 BMW 760 V12 6.0L Twin Power Turbo Standard with 70000 km mileage, I considered the listed prices of similar cars. The 2018 BMW 760 M xDrive V12 6.6L Twin Power Turbo with 46640 km is listed for SAR 276000, and the 2017 BMW 760 W12 6.6L Twin Power Turbo LD with 26000 km is listed for SAR 275000. Given that the car in question has higher mileage, I adjusted the price downwards. The average listed price is SAR 275500. Considering the higher mileage and the fact that listed prices are generally higher than selling prices, I estimated a lower market price for the car in question.
