Welcome to the site :cool:
As this site is focused exclusively on bikes, I doubt that you would get anyone that wants a quad, but I will say that your heart is in the right place. You can go much faster, do far less damage to the environment and raisse your fun quotent by a huge margin on a bike. I know it doesn't look like it outside, but spring is coming. I would suggest putting that quad in the classified section of the paper. There is somebody in the KC area just itching to have a quad in their garage. If you can get your asking price there are a bunch of bikes in your price range.
Again, welcome to the site, and shout if you have any questions!
