Are you on eBay with it? Rather than start bidding at $400, set a $400 reserve sell price. That way you get bidders. If nothing else you can identify who they are and what their limits are for your item. If it doesn't hit the reserve, you can always relist it with a lower reserve, or make a Second Chance offer to the high bidder.

$400 seems fair for all of the bling on that truck. It just might not be everyone's "cup of tea". Maybe convert it back to stock trim and sell the aluminum stuff stand-alone? At $400 I would bet most folks will just pony up a few more dollars and get a brand new Revo.
