In this blog entry I've added all confirmed Repulsorlift vehicles that operate and can be seen in the saga. You won't find any kind of Walker, wheel of thread driven vehicles, underwater vehicles or vehicles driven by animals, wind or droids.

You can find the name of the vehicle, the company that made it and the episode it can be seen. Sometimes the vehicle carries a name of it's own.
