i generally favor the free for all idea. But i'm thinking there could be themes---winners in each category and then an overall/free for all winner out of the themes. The overall winner would be the top prize.
P.S., here is another theme idea----stock, daily driver. i'm biased towards my truck.
The other thing is, i feel there should be a detailed description of the inner workings---the drivetrain, interior, any other special things about the truck included in the description; It shouldn't just be judged on looks alone.
We, as a society, tend all too often to judge a book by it's cover and..............
What i'm trying to say is i don't think we should go just by looks alone, but that's just me.
