If you're a Model S owner about to trade in your Model S on a new P85D, 70D etc. have you thought about your parcel shelf? For many the parcel shelf wasn't free, it was a $250 upgrade which seemed a lot for what it did. When your trade in is valued you will most likely not receive any extra money for the fact that you have a parcel shelf (I have yet to find any evidence that they credit you for it). Why not sell it or charge a nominal rate to cover shipping etc to an existing owner? You could either: a) Make a few extra $ on your trade OR b) Make an owner without the parcel shelf very happy to get a bargain. One method is Ebay of course. Another is by having people who are interested in getting one posting here and then doing a direct message to them if you have one to unload prior to the trade in. Consider me interested but only if its basically just shipping.
