I analyzed the selling prices of similar cars first. The most relevant data points are: 2013 Porsche Cayenne GTS with 195046 km sold for 60000 AED on 2024-09-22, 2014 Porsche Cayenne GTS with 236000 km sold for 61500 AED on 2024-09-04, and 2013 Porsche Cayenne GTS with 144900 km sold for 54500 AED on 2023-06-25. The car in question has higher mileage (231700 km) and is in average condition. Considering the higher mileage and average condition, the price should be slightly lower than the 60000 AED and 61500 AED cars. The listed prices of similar cars range from 58000 AED to 103000 AED, but these are generally higher than actual selling prices. Therefore, I estimate the market price to be slightly lower than the lowest recent selling price of 60000 AED.
