I was listening to a great Podcast with Dean Lanzante recently and thought it might be best to correct myself on the models:
There are now two P1 'Longtail' options: the P1 GT and the P1 GTR-18. These came about after Dean was approached by a customer who wanted a P1 LM after the run of 5 production cars and 1 XP (based on P1 GTR #049GTR) was completed. Dean says to the effect that he had wanted to do a project like this and thus the P1 GT project began.
The P1 GT is the road spec variant, limited to 3 units with a GT feel. It has a stereo, electric windows, sound proofing, carpets, road seat belts, etc. Each will reflect the specs of the 3 F1 GTs.
01, The original car was the green car, with harks to the prototype F1 GT #56XPGT which was owned, until recently, by the factory. This is based on P1 GTR #033GTR
02, The second car is in build/just completed, as per Greg's post. I believe its look reflects F1 GT #58F1GT - a gorgeous car which was resprayed in recent years. This is based on a 'normal', street P1 - #020.
03, The third car pressumably will ape the last F1 GT #54F1GT, owned by the Brunei Royal Family from new. What car it is built on remains to be seen.
The P1 GTR-18 is the track variant that Lanzante has devised. It lacks the stereo, has driver and passenger headsets, no sound proofing or carpets, solid windows, is another 40kg lighter(!), and so on. The specs of these are said to intend to correlate with the F1 GTR-97 (aka the F1 Longtail).
01, The first car built comes in the Davidoff Livery as seen above, being based on P1 GTR #011GTR.
Subsequent cars remain to be completed/seen!
Production continues, according to Dean so it will be great to see what comes next! Each customer needs to come with a donor car and a large pile of cash...and the balls to modify a 'hypercar'
