Ideas for indoor carshow display

Need some pics or ideas for indoor show displays. I know sign board and stantions. Im talking about little things go make one go one up from just a "good looking display". Or would you rather just see a car on some clean carpet, some mirrors, and a display board?

I know I've seen things sitting out with a car and it looked good, gas, water, oil cans etc...Im just trying to get some thoughts and ideas in case I do one.
