I am not a fan of the crop and angle you have applied to this image. The top of the roof has been cropped off, as well as the lower part of the pumps and car. I don't see how either crop helps the photo. Using such traditional elements, a more traditional angle and crop with space, using rule of thirds and the like, I feel would be much more suitable. The subject matter is great for this (I wish I had this for the challenge).
The car is very dark. Some light from the front to light the car and the front pump would have been great, and made them more prominent, withot blowing out the front sign and areas already lit.
