To estimate the price of the 2012 Porsche Panamera Turbo V8 4.8L Turbocharged Turbo Executive, I first looked at the selling prices of similar cars. The closest match is the 2011 Porsche Panamera 4S V8 4.8L Turbocharged with a selling price of 110000 SAR, but it has a lower mileage (59382 km) and is in good condition. Another relevant data point is the 2014 Porsche Panamera 4S V6 3.0L Twin Turbo, sold for 84000 SAR, but it has a different engine and higher mileage (129000 km). The 2013 Porsche Panamera V6 3.6L sold for 71000 SAR, but it has a different engine and much higher mileage (208077 km). Considering the listed prices, the closest match is the 2012 Porsche Panamera Turbo V8 4.8L Turbocharged listed for 119000 SAR, which has the same mileage and specs. However, listed prices are generally higher than selling prices. Taking into account the car's age, mileage, condition, and the depreciation over time, I adjusted the price downwards from the listed price to reflect a more realistic market value.
