To estimate the price of the 2019 BMW X5 V6 3.0L Twin Power Turbo xDrive 50i (Top), I focused on the listed prices of similar cars since there were no selling prices or offers accepted. The closest match is the 2019 BMW X5 V8 4.4L Twin Power Turbo xDrive 50i (Top) with 102,000 km listed for SAR 192,000. Another relevant listing is the 2019 BMW X5 xDrive 40i I6 3.0L Twin Power Turbo (Mid) with 117,132 km listed for SAR 160,000. Considering the target car's mileage of 110,500 km and its V6 engine, I estimate its price to be slightly lower than the V8 variant but higher than the xDrive 40i due to its higher trim level. Thus, I estimate the market price to be around SAR 180,000.
