Car appreciation... the aesthetics, the engineering, etc

The fastest production car in the world...The 9ff GT9 has recently recorded a documented top speed of 409 kilometers per hour, or 254.1 mph, enough to knock the Bugatti Veyron down to third on the list of all time fastest production cars.

Where do they test this and what numbers are they required to produce before it's a "production car"? That thing ^^ doesn't look very factory to me. :)
