And no one wants a trip in the most reliable hunk of junk this side of Corellia?
After that I think it may have to be a tie between the X-Wing and Y-wing.
Depends: MAAT, AT-HE, AT-OT, or the SOVEREIGN-class Super star destroyer. All of them are so fun to use.
Nebula-class Star Destroyer. A New Republic star destroyer the same size as an ImpStar Deuce, but able to easily combat a SSD.
YT-2250. Coolest ship ever from the coolest manufacturers ever.
