Welcome, Michelet. You might want to check out the website/blog I built as I was constructing my first art car at
www.MutantVehcle.com and maybe you can learn from some of my mistakes and discoveries. It would also be helpful to own a time machine because there is precious little time to build one correctly before this years burn. If you slop it together and the Department of Mutant Vehicles does not approve, you could find it at the impound lot for the entire event.
Follow this like an art car bible:

Good luck, and I hope to have a minor collision with you on the playa!
