To estimate the price of the 2012 Porsche Panamera 4S V6 3.6L Standard with 151500 km mileage, I considered the following data points: A 2014 Porsche Panamera 4S V6 3.6L with 135000 km is listed for AED 80000. Given that the 2012 model is two years older and has higher mileage, I adjusted the price downwards. Additionally, a 2013 Porsche Panamera 4S 4.7L V8 TC with 77000 km is listed for AED 128000, but this car has a different engine and lower mileage, making it less comparable. Considering the age, mileage, and condition of the target car, I estimated the price accordingly.
