To estimate the price of the 2021 Porsche Cayenne V6 3.0L S (Mid) with 82000 km mileage, I first looked at the selling prices of similar cars. The most relevant data point is the 2020 Porsche Cayenne V6 3.0L S (Mid) with 77000 km mileage, sold for SAR 255000 on 2024-03-19 and 2024-03-20. Another similar car sold for SAR 220000 on 2024-04-16. Considering the car in question is a year newer, I adjusted the price upwards slightly. I also considered the listed prices of similar cars, such as a 2021 Porsche Cayenne V6 3.0L S (Mid) with 82000 km listed for SAR 327000, though this is likely higher than the actual selling price. Other listed prices for similar models range from SAR 224000 to SAR 310000. Based on these data points, I estimated the market price by averaging the selling prices and adjusting for the newer model year and higher mileage.
