To estimate the price of the 2017 MINI Cooper Twin Power Turbo I3 1.5L 3-Door, I first considered the selling price of a 2019 MINI Cooper I4 1.5L S 3-Door with average condition, which sold for SAR 76000 in June 2024. This car is newer and has a more powerful engine variant, so the 2017 model should be valued lower. Next, I looked at an offer accepted for a 2017 MINI Cooper JCW John Cooper Works I4 2.0L, which was SAR 68000. This car is a higher performance variant, so the target car should be valued lower. The listed price for a similar 2017 JCW model was SAR 72500, but this is likely higher than the actual selling price. Considering these data points, the 2017 MINI Cooper I3 1.5L should be valued lower than the JCW variant and the newer 2019 model, leading to an estimated market price of SAR 55000.
