Just an awesome shot and colors!! Are you using nik color effex for this look? I use the software and have used the filters that give the same look. Just curious.
Vipgraphix: The timing of the shot was important, I had arranged to shoot it about an hour before sunset to get the orange hue - I added to this further in PS by an orange gradient (I did not want to ruin the sky). Then used an image channel (I think it was the green one) as a semi-transparant soft light layer just to give the image some OOmpf.
It's an amazing car - it took a him a couple of years to restore a rusty wreck to this condition.
