C&C per req: Well, it's a start, but IMO, you have a ways to go. The cloning needs more effort, and in the process you've induced blown highlights into the lights on the front bumper. The secret here is to start with a good image to begin with. You needed a large, diffuse light camera left to improve the exposure as well as a much larger aperture to render the background more diffuse and less distracting. Also, don't forget the small things: Scrub the dirt off of the exposed areas of the tires and wheel-wells, and consider a polarizing filter to reduce some of the reflections.
Just my $00.02 worth - your mileage may vary.
