While i do prefer the 2007 basic layout and recent illusion mariner color (i think it is called like that, color that change with illumination) that i find just gorgeous, regret the appendices on the cars.
I mean i love the front wings noses of this year, especially the ferrari one, barge boards , end plates and rear wings are fluid to me, but all the vortex generators everywhere especially on sidepods just make the thing overloaded....in that i prefer the F2004.
But that's true also this is because the 2004 was just a hell on track.
