To estimate the price of the 2018 BMW 740 Li Twin Power Turbo I6 3.0L Top, I first considered the selling price of a 2016 BMW 740 I6 3.0L Twin Power Turbo with average condition, which sold for SAR 109,000 in September 2023. This car is older and in average condition, so the 2018 model in good condition should be valued higher. Next, I looked at listed prices of similar 2018 models. A 2018 BMW 740 Li with similar specs and lower mileage was listed for SAR 160,000 in May 2024. Considering depreciation and market trends, this suggests a price range for the 2018 model. Additionally, a 2016 BMW 740 Li with similar specs was listed for SAR 126,000 in October 2024, indicating that the 2018 model should be priced higher. Taking into account these data points and the condition and mileage of the car, I estimated the market price.
