@ CoolbeaN: Thanks!, Tutorial: 1. I used Magic wand tool to select car body 2. then I used Hue and Saturation to choose new color 3. I made clean up work to finish picture.
I love the GT-ONE shots, I did that same car on that same track, with that same mature feel to it, gotta love it. The Civic shots is good too, I like the darkness of the pic.
