To estimate the price of the 2013 BMW 750 Li V8 4.4L Twin Power Turbo with 236000 km mileage, I first looked at the selling prices of similar cars. A 2014 model with 90000 km sold for 84000 SAR in December 2023, and a 2012 model with 159000 km sold for 45000 SAR in May 2024. Given the higher mileage of the target car, its value would be lower. Next, I considered listed prices: a 2013 model with the same mileage is listed for 71500 SAR, but this is likely an overestimate. Another 2013 model with 221000 km is listed for 37000 SAR, which seems more realistic. Considering the depreciation and the condition, I estimate the market price to be around 40000 SAR.
