Aston Martin One-77 already being delivered to customers details

After years of hype, it appears the first customer has taken delivery of their new Aston Martin One-77.
While it seems unusual for the company not to promote such an event (they sent out a press release for the first delivery of the Rapide), a black One-77 was spotted in front of the Hotel de Paris in Monte Carlo wearing non-manufacture plates. This seems to imply the car is a retail model, but we cannot confirm it.
 

Regardless, the supercar features a 7.3-liter V12 engine with 750 hp (559 kW / 760 PS) and 750 Nm (553 lb-ft) of torque. Official performance specifications haven’t been announced, but the One-77 is expected to accelerate from 0-100 km/h in 3.5 seconds and hit a top speed of 220 mph (355 km/h).
