Today i got to sit in the 4th Mclaren ever made. it had expermanal project written all over it. i rich dude in my nieborhood bought it from someone in new zeland a year ago and just got it today. i got to his house right after he drove it, that engine puts off so much damn heat you could not even get that close. it was nuts! he said tat their are only 3 expermntals, xp3 (ownded by the desighner), xp4 ( owned by him), andthe xp5 (owned by McLaren). he is the second owner of the first McLaren ever sold to the public.
