Gluk, Stock, and Two Smoking Lasers
Got a ship parked (or crashed) somewhere? Quekko's Choice Ship Emporium, purveyor of the finest pre-owned vehicles and vessels, will pay cold hard Underworld Credits (or trade-in value!).
OOC/ My only caveats are that the ship needs to be one of the six thousand subs in the Approved Starships forum, and that you should actually own it IC in some way. Also you would probably not be happy with how little Jerec could pay for a Star Destroyer.
