To estimate the price of the 2021 MINI Cooper Twin Power Turbo I4 2.0L S 3-Door, I first considered the selling prices of similar cars. A 2022 MINI Cooper I4 2.0L S 3-Door with 26000 km sold for SAR 151500 in April 2024. A 2019 MINI Cooper I4 1.5L S 3-Door with 13000 km sold for SAR 76000 in June 2024. The 2021 model should be priced between these two, considering its age and mileage. Next, I looked at listed prices. A 2020 MINI Cooper S 3-Door with 44094 km was listed for SAR 87500, and another 2020 model with 41000 km was listed for SAR 92500. These listings suggest a price range for a 2021 model. Considering the 2021 model's mileage of 54000 km, which is higher than the 2020 listings, I adjusted the price slightly lower than the 2020 listings. The 2021 model's engine size and variant match the 2022 sold car, but its higher mileage and older year suggest a lower price than the 2022 sold price. Therefore, I estimated the market price to be slightly below the 2020 listings, considering depreciation and mileage.
