Chrysler 300 Customization (and youtube event)

I posted yesterday about custom shoes, and noticed moments later this TV about customizing your Chrysler 300.

It turns out, it's a video contest as well, with a dedicated page on YouTube: YouTube.com/Chrysler300. (No, they don't give you your car if you win.) How crazy.
Ironically, though it doesn't show on this YouTube cut of the TV ad, the aired version ends with:
"Upload videos of your own customized 300 and your ride could get a place of honor at one of our events. (fine print: No purchase necessary...).
No purchase necessary?!
The complete rules are here, but don't clarify how to enter this contest without buying a car.
I hereby launch a spin-off contest, "Spin Your Neighbor's," where you customize a Chrysler 300 you didn't actually purchase. Go ahead and upload it as part of Chrysler's contest; we'll judge entrants there. ;-)
