To estimate the price of the 2011 Maserati Quattroporte 4.2L V8 GTS, I considered the following data points: 1) The listed price of a 2009 Maserati Quattroporte S with 93000 km is AED 28000. 2) Classified listings for similar cars: a 2011 model with 150000 km listed for AED 55000, a 2010 model with 98000 km listed for AED 95000, a 2012 model with 62000 km listed for AED 69500, and several 2010 models with mileages ranging from 35643 km to 49000 km listed between AED 65000 and AED 78000. Given the higher mileage (169980 km) and average condition of the target car, I adjusted the price downwards from the classified listings. The 2009 model's lower price also influenced the estimate. Considering depreciation and the higher mileage, I arrived at a final estimate.
