They add a marginal value to a used car but nothing spectacular. Empty boxes can sometimes fetch quite reasonable sums on eBay and sometimes not. May be worth a try if you don't mind the hassle. Otherwise see if you can shift some on here in the sales section. It would be a shame to bin them and environmentally unfriendly. I have often just given my surplus boxes away for free, there is usually somebody on the various forums who want them.
