I had to change my Lego McLaren MP4-26 to convert into the MP4-27
I have added more detail with a black marker pen but i fear i have ruined the pieces :/
It took me along time to try and get it as accurate as possible because all i had was a few images because McLaren had unveiled their new car only recently.
Yeah i did Well a few years ago i bought a race car from Megabloks and took it apart and i have recently built the McLaren Mp4-26 and the 27 using some of those parts. And to answer yor question, yes, i made this up myself
