Odds of winning are better if you enter then if you don't. You should see some of the P.O.S. cars people bring to the local car show here. I'm talking Chrysler K cars with 22's lol. Trust me, you got a better chance then they do!
go for it man. see the reaction u get from the crowd and build on that with your car. i love going to shows and getting new ideas from fellow car enthusiast. you have nothin to loose. so bring out the balt!! lol
good luck too!!
