I did a lot of stuff to that pic. Shaving (clone tool), clear corners (desaturate/levels), billet grilles (line tool), wheels (cut and paste and a little coloring, also re-cut the center on the rear to give it a better angle and deep dish look), the 2-tone was by making the top a new layer and adjusting levels, brightness/contrast and/or a fill effect, the graphics were hand drawn, then given some effects (drop shadow, and belel/emboss on the green).
