This song is half-parody: it's basically a sleazy car salesman's sales pitch to a potential buyer on 'the finest ship in the galaxy'. There's actually a plot to the entire album that I don't know in full, but I think this is near the end where this character is looking to get a ship of her own to travel the stars as part of a larger quest. Also, the shot on top of the ship with the red jacket is from Gunbuster, Daibuster, Harlock, Gurren Lagann, and like a dozen others. It's called the Gainax Pose, and became a signature 'thing' for Gainax Studios to include in their sci-fi stories, and tons of other series have paid homage to it.
