I quite like this shot. Personally, the only thing I would have changed would be it's sharpness but I understand you have tried to sharpen it already. It's just a little blurry. However, in some ways it adds to the photo.
Gran Turismo has a Photo mode which allows you to place the car in different scenes. Then you have the option to tweak the camera settings such as aperture/shutter, angle and some post processing. It's pretty close to taking a real photo.
One of your better car shots in your portfolio. I've compared it to your previous version of this shot and the only thing I can really suggest is to somehow bring out the wheel arches. it might be a personal preference though. At the moment, due to the lack of lighting, the arches look really really wide or even missing. I think it's onto a winner though. It reminds me of one of AmbientLifes:
