Hey Neo,
Are you the same Neo that is over at the Neon.org?
Anyway, my friend has a contour GL and tried locating sideskirts from an SVT and didn't have any luck. So I say good luck to you trying to find them without buying them new from dealer($$expensive$$) Anyways, I would say get performance parts first and make it fast before changing it's appearance. I went the appearance route first with my Neon and now I am working on performance speed aspect. I wish I would have done the performance stuff before I put the tons of $Money$ into the appearance of my car.
The best of luck to modifying your Tour!
Brian
