The box is pretty beat up buddy and the damage to the ship will significantly reduce the value i would say place at auction on eBay and described correctly it will sell for £20 - £40 buddy.
For example one sold on ebay recently for £75 and that B-WING was in mint condition with working electrics, no yellowing and a decent box with no damage.
Might not be ideal considering what you paid 8 years ago but i hope that helps mate

Cheers Jay
