I started by examining the selling prices of similar cars. The 2015 Porsche Cayenne GTS V6 3.6L Twin Turbo with 138,000 km sold for 110,000 SAR in April 2024. This car is a higher variant (GTS) than the target car, which suggests the target car should be priced lower. The 2014 Porsche Cayenne V6 3.6L Turbocharged with 127,000 km sold for 76,500 SAR in October 2023. This car is older and has a different engine configuration, but it provides a lower bound. The 2014 Cayenne S V8 4.8L Twin Turbo with 187,000 km sold for 90,000 SAR in November 2023, which is a similar variant but with a larger engine. The 2013 Cayenne V6 3.6L sold for 110,000 SAR in January 2024, but it had much lower mileage. Considering the listed prices, a 2015 Cayenne S V6 3.6L with 165,000 km is listed for 118,000 SAR, and another with 186,000 km is listed for 100,500 SAR. These listings suggest a market range. Given the target car's mileage of 147,000 km and good condition, I estimate its price to be slightly below the higher listings and above the lower selling prices.
