That most of the ships are almost 3000 years old.  That outside three other hangers on this floor, they're mostly short-range fighters or troop transports with no Hyperdrives to speak of.  The Darth ship is apparently on the direct opposite side of this station.  It's also the only place that has a functioning camera, and it shows the entire bay, alone with a Tie-Fighter like craft in it.<br/><br/>(http://images2.wikia.nocookie.net/__cb20100616160027/starwars/images/8/89/Imperialfury.jpg)<br/><br/>Oh, and um, Sully?  Most people wouldn't know about wheeled vehicles.  If you want to claim that your home (or a planet you've been on) has them, that's perfectly fine, just most other inhabitants would look at the phrase funny. :)
