Talking from an honest buyers perspective, any reputable company selling a full interior such as this one will almost certainly be expecting calls regarding its provenance. If they wish to achieve anywhere near the price being asked here, they will need to come up with both proof of origin and the reason for the sale. Obtaining written reassurance on this point should be any buyers first course of action. Stage two should be a full physical inspection of all parts before bidding. For a 2018 Ocean to have been scrapped ligitamately it would have to have recieved substantial damage, enough to write it off. Any incident causing that much damage may well have damaged the interior as well. Then there's the care or lack of when removing said interior. If it were me, I'd be looking for cracks, stress damage, broken fixings and any other marks etc before even thinking of bidding.
Anyone interested should check, check and check again before doing anything. I would also try to establish who the previous owner was and attempt contact them to check the information given.
This interior isn't from the OP's Ocean. It has the wrong interior and exterior colours.
