The car to be estimated is a 2020 Porsche 718 Cayman I4 2.0L Turbocharged Standard with 45500 km mileage. We have an offer accepted for a 2021 model with the same engine and variant at SAR 255000, with a mileage of 11700 km. The listed price for the same 2021 model is SAR 267000. Considering the 2020 model is a year older, we apply a depreciation of approximately 10% per year. The 2020 model has higher mileage, which further reduces its value. The accepted offer for the 2021 model is SAR 255000, so a 10% depreciation for one year would suggest a price around SAR 229500. Considering the higher mileage, we adjust the price downwards to account for the additional wear and tear.
