Discussion: Method for user voting about best looking cars

[Madman]

Simple. everyone who wants to participate tell the staff of the event about it.
Then we have list of like 50-100 cars. And then all the people votes for 5-10 best cars in their opinion. Can't vote for yourself. The car which have the most votes wins.
The problem is, how to organize it technically.
Can you make such a thing in strawpoll? Because voting like this on chat or something wont work.
I think its good idea, everyone would be happy. But the technical side... ehh...
