The Roaring Tornado was an Arrow shuttle loop. From what I was told, the coaster was bought new for around $300,000., and was sold because the park was cash strapped, and bills needed to get paid.
When Six Flags Elitch Gardens came to look at the ride, it had already been winterized. Magic Springs got the ride up and running with short notice. Six Flags did not even bother takeing a ride, they just bought it. The ride still operates there today.
