The closest match in the selling prices is a 2015 Cayenne GTS V6 3.6L Twin Turbo with 138000 km sold for 110000 SAR in April 2024. Given the lower mileage of the target car, it should be valued higher. Another relevant data point is a 2014 Cayenne GTS V6 3.6L Turbocharged with 127000 km sold for 76500 SAR in October 2023. The 2016 model year and lower mileage of the target car suggest a higher value. A 2016 Cayenne GTS with 115000 km was listed for 159000 SAR, but this is likely higher than the market value. Considering these factors, the estimated market price is adjusted upwards from the 2015 model's selling price due to lower mileage and newer model year.
