I've looked around a bit with Google and I haven't found it, so I'll ask here. Is any place selling a cup holder accessory you can attach or put into the Model S yacht floor to add cup holders? I don't necessarily want to spend a full $500 on that Evannex drop-in center console, and I definitely don't want to spend $1250 for the official Tesla center console just to add cup holders which should have been in the S on day 1. I have seen on Ebay different cup holder accessories which are meant for other cars which also have similar yacht floors. If there isn't specifically one for the S, would one of these fit into the yacht floor on the S? Any help would be appreciated! Thank you!
