You can buy off camera flash and place them were ever you want, then just sync it to time with your camera. Or just experiment with any lights, bright torches or small lamps placed in the right place. You could also do HDR photos which will give you details in the picture that you cant get with single shots.
This picture is HDR it is actually 6 pictures blended into one, because it is a dark garage it is impossible to get the details around the bottom of the splitter and also capture the light reflections on the bonnet and back of the garage all with one exposure. Exactly the same problem you have with your picture.
