Orange Liveried MP4-21 from pre-season testing
the green and yellow Lotus from this/last year
i LOVE the deep blue of the modern day redbulls too
1977 Brabham - martini racing
the 'elf' liveried tyrrells.
5 worst:
the two Honda 'earth cars'.. nice idea, and in an ideal world, they would work, but we're not, and they just didnt.
the '94 pacific racing liveries were pretty awful.
brabham BT34..
1999 B.A.R. Both liveries looked nice when apart, one of them may even have featured in my top five, but two together just dont work. and yes, i know it was the FIA wanting them to have both cars the same, but they should have picked one, and stuck with it!
and just a final note as well, a bad livery will look okay on a beautiful car, and a nice livery may look awful on a bad car in my opinion....
