I was involved in a similar effort a few years ago. Take my word for it, it's worth any amount of effort you put into making something like this happen.

Photos, photos, photos. Don't forget to take some of the people as well as the cars.
Try to get there as a group. The impact of bunch of Cobras rolling in together is significant.
Congratulation to all who have a chance to participate.
