To estimate the price of the 2013 BMW 520 I4 2.0L Twin Power Turbo with 187706 km mileage, I considered the following data points: 1) Selling prices of similar cars: - A 2013 model with 234000 km sold for 31500 SAR on 2023-12-17. - A 2013 model with 176000 km sold for 35000 SAR on 2024-08-01. - A 2012 model with 155500 km sold for 37000 SAR on 2023-11-11. - A 2013 model with 271000 km sold for 32000 SAR on 2023-12-17. - A 2012 model with 197000 km sold for 35000 SAR on 2023-12-24. 2) Listed prices of similar cars: - A 2013 model with 187706 km listed for 52000 SAR. - A 2013 model with 176000 km listed for 38000 SAR. - A 2013 model with 234000 km listed for 37000 SAR. Considering the selling prices, the average price is around 34100 SAR. The listed prices are generally higher, so they were used as a reference but not as the primary basis. Given the mileage and condition of the car in question, I adjusted the estimate slightly below the average selling price to account for the higher mileage compared to some of the sold cars.
