To estimate the price of the 2014 Porsche Panamera 4S V6 3.6L Standard with 135000 km mileage, I considered the listed prices of similar cars. The 2012 Porsche Panamera 4S V6 3.6L with 151500 km is listed for AED 58000. Given that the 2014 model is two years newer and has slightly lower mileage, it would typically be valued higher. The 2013 Porsche Panamera 4S 4.7L V8 TC with 77000 km is listed for AED 128000, but this car has a different engine and significantly lower mileage, making it less comparable. Considering the depreciation and the average condition of the car, I adjusted the price of the 2012 model upwards to account for the newer year and lower mileage.
