MartijnGizmo wins it for me.
I know i must have said how much i like his picture about a million times already, but it really is fabulous.
The car is average - an M3 really isn't a rare sighting anywhere.
The green vs blue looks fantastic, and the panning is supercrisp, especially after taking into account the slow shutter speed (which i assume helps to keep the colours vivid).
Others worthy of mention.
jon_s - a nice tyre smoking shot
Maou/Symylait - both of the orange Zonda look cool
Speedracer38 - just because of the rareness of the F50 and Enzo (plus the red and yellow look great together.)
80ssportlover - nice shot including the bridge. The yellow of the pontiac looks fantastic.
eurocopter - a menacing RS4 - looks fantastic
Congrats to everybody who made it into the poll - but hats off to Martijn 8)
