To estimate the price of the 2013 Bentley Continental 4.0L V8 Twin Turbo Charged GT W12 Speed (Top), I considered several data points. First, a 2015 Bentley Continental S 4.0L V8 TC with higher mileage (114250 km) sold for AED 174000 in October 2023. This car is a newer model but a lower variant (GT V8 S Base). Next, a 2013 Bentley Continental 6.0 Turbo W12 (GT W12 Speed Top) with higher mileage (103700 km) had an offer accepted at AED 144000 in May 2024. This is a similar variant but with a larger engine. Additionally, a 2013 Bentley Continental 4.0L V8 (GT V8 S Base) with similar mileage (95500 km) had an offer accepted at AED 132000 in November 2023. For listed prices, a 2013 Bentley Continental GT V8 4.0L Twin Turbo (GT W12 Speed Top) with slightly lower mileage (82000 km) was listed for AED 145000. Another 2013 Bentley Continental 6.0 Turbo W12 (GT W12 Speed Top) with higher mileage (103700 km) was listed for AED 160000 but delisted in July 2024. Considering these data points, the estimated market price for the car in question is derived by averaging the accepted offers and adjusting for the specific variant and condition.
