I was trying to capture the color of the vw.
"Car show", huh? It appears to be a very low budget car show with so many cars crammed into a too-small space. Not enough space to properly stage and light them. Also, I see that you were using only ambient light from the ceiling fixtures.
Perhaps you could approach the producer of the show and ask if any of the cars can be repositioned in an effort to get better photographs. Alternatively, you could talk with each owner in turn to ask if they would be willing to allow some photography.
