Pictured here is P1 GTR chassis #001. This isn't the first car built, however, and is not in its original specification. When this car was first produced, it was in the Geneva launch specification of yellow with green stripes, reminiscent of F1 GTR #06R. Following it's build, it was sent to Lanzante to have a road conversion, and became the 3rd car to be converted. It was then shipped to the US, where the green stripes were changed to red, as well as the orange 'GTR' stickers, and 01 was added to the car, for example on the doors. This was the first of 2 'road legal' P1 GTRs that are currently in the US - it'll be interesting to see if any more make it there.
