To estimate the price of the 2021 BMW 218 Gran Coupe I3 1.5L Twin Power Turbo (M Kit) Standard, I considered several data points. First, a similar 2020 BMW 218 with higher mileage (88000 km) sold for SAR 110000 in February 2024. Given the lower mileage (10700 km) of the target car, it should be valued higher. Next, an offer of SAR 129000 was accepted for a 2021 BMW 218 with similar mileage (10000 km) in September 2023. This suggests a higher value for the target car. Additionally, the target car is listed for SAR 154000, but listed prices are generally higher than actual selling prices. Considering these factors, I estimated the market price by balancing the lower selling price of the older car and the higher accepted offer for a similar car.
