Bling... that's the glitter and sound of those big, shiny chains some men love to wear ... so if you're bling, you're big, shiny, expensive, etc. Check out the drivers of the BlingBus! Wedge is piloting, Biggs is navigator, and Wedge made Biggs sit between the squadron goofballs to separate them. Poor Biggs! (Can you hear Wes leaning across Biggs to whisper to Hobbie, "You want to tell Wedge about the signs?")
Many thanks to StarWars.com and the owner of the Bus, whoever he/she is!
