Photograph it with the sun on it. Put in on the lawn (or on a small table) and get your camera *right down* next to it so it looks like a realistic viewpoint. Try it on the grass, or with your house as the background or with your white mini-backdrop. (blacktop is too dark - if you put it on the tar, then try to keep it out of the photo - ie. point the camera up slightly.) Get the car to fill up the photo more.
At the moment it looks like it's in the garage, on a dirty uneven bit of paper, lit by a single strip light. If you can't get sun or even outside, put as much light as possible on it - a 400-watt work light, and get that camera on the ground, and a mini-tripod (or put the camera on the ground / a couple of books) and use the self-timer.
