To estimate the price of the 2021 Peugeot 3008 GT Line I4 1.6L Turbocharged with 82000 km mileage, I considered the following data points: 1. Selling prices: A 2019 model with 61000 km sold for SAR 72000 in November 2023, and a 2023 model with 37889 km sold for SAR 107000 in July 2024. 2. Listed prices: A 2021 model with the same mileage is listed for SAR 93500. A 2019 model with 67000 km was listed for SAR 82500. A 2023 model with 37889 km was listed for SAR 112000. 3. Depreciation: Assuming a 10% annual depreciation, the 2021 model would have depreciated approximately 30% from its new price. Considering the selling prices, the 2021 model's higher mileage, and the listed prices, I adjusted the estimate accordingly.
