Let's look at presentation for a minute...
From the rules:
“Presentation” covers things like originality, theme, showmanship, team spirit, moxie, chutzpah, backstory and anything else that falls under the heading of “je ne sais quoi.”
I have no idea why so many people think this means you have to sing a song or ride a pony.
Originality? Backstory? These have EVERYTHING to do with the car and NOTHING to do with a circus performance. Pete Gossett told us about the woman he bought the car from and her son that passed away. Made us understand why this was important to him.
If ALL you care about is a hunk of metal, you are at the wrong event. It's about the editorial content- they are trying to write a magazine.
Moxie? Chutzpah? The Smith team had both in spades. Never did anything weird.
Team spirit? Hang with the turbo dodge guys for a while... OK, sometimes those guys will put on a cop uniform or paint their car like a box of cornflakes, but it's ALWAYS about the car. And let's face it- they can whoop most of us on any track.
Most teams that scored well for presentation simply told us cleanly about their car. Some actually rehearsed their presentation (it helped a lot).
You can't expect a judge who has never been to the event, never heard of you, never read the forum to be impressed when you stick a hunk of metal in front of them. They won't know if you don't tell them. Same thing for the readers.
So, tell them you traded a bicycle for it, but ALSO tell them how hard it is to build an FSP car, what an FSP car is, and how many hours you worked at getting it to the point it is now.
Im not big on offers for free alien probes.
