To estimate the price of the 2012 BMW 740 V6 3.0L Twin Power Turbo Top, I first considered the selling prices of similar cars. A 2011 BMW 740 I6 3.0L Turbocharged with 203,000 km sold for 43,000 SAR, and a 2013 BMW 740 V6 3.0L with 227,000 km sold for 49,500 SAR. A 2014 model with 231,000 km sold for 62,000 SAR, but it was in average condition. The 2012 model in question has higher mileage at 257,500 km and is in average condition, which suggests a lower price than the 2013 model. I also looked at listed prices: a 2012 BMW 740 V6 3.0L with 182,000 km was listed for 38,000 SAR, and a 2012 BMW 740 Li I6 3.0L with 149,000 km was listed for 51,000 SAR. Considering the higher mileage and average condition of the car in question, I estimate its market price to be slightly lower than the 2013 model's selling price and closer to the lower end of the listed prices.
