To estimate the price of the 2013 Porsche Cayenne S V8 4.8L (400 Horsepower) with 174000 km mileage and average condition, I considered the following data points: 1. A 2014 Porsche Cayenne S V8 4.8L Twin Turbo with 187000 km in good condition sold for 90000 SAR on 2023-11-25. 2. A 2013 Porsche Cayenne V6 3.6L with 89000 km in average condition sold for 110000 SAR on 2024-01-19. 3. A 2012 Porsche Cayenne V8 4.7L with 189000 km in average condition sold for 64500 SAR on 2024-07-16. 4. A 2012 Porsche Cayenne V8 4.8L with 216000 km in good condition sold for 55000 SAR on 2023-09-23. 5. A 2012 Porsche Cayenne V8 4.8L with 287000 km in average condition sold for 48000 SAR on 2024-03-30. 6. A 2013 Porsche Cayenne V8 4.8L Twin Turbo with 221000 km listed for 77500 SAR but delisted on 2024-06-28. Considering the car's age, mileage, and condition, I adjusted the price downwards from the higher end of the range, given the average condition and higher mileage compared to some of the better condition cars sold recently.
