To estimate the price of the 2014 BMW 730 Li I6 3.0L Twin Power Turbo Li (Top) with 222000 km mileage, I considered several data points. The most relevant selling prices include a 2014 BMW 730 Li I6 with 110000 km sold for 71874 SAR on 2024-07-16, and a 2012 BMW 730 Li I6 with 219194 km sold for 40500 SAR on 2024-06-04. The 2015 BMW 730 Li I6 with 62700 km sold for 82000 SAR on 2024-06-27 is also relevant but has much lower mileage. The listed prices for similar cars are 47000 SAR and 68500 SAR, but these are generally higher than actual selling prices. Considering the higher mileage and average condition of the target car, I adjusted the price downwards from the 71874 SAR benchmark, factoring in the higher mileage and average condition.
