250S W108 Decommissioned for 12 years, what to do?

A friendly Moin Moin from Hamburg As a result, the thing is there: The car has been logged out for 12 years, was standing 6 years in a rather damp garage which has pretty much added to him, and then another 6 years in a dry garage.. The question is now what should we do with the car? So, directly sell as it stands now, completely restore so that it is almost original where the question is with how much € you can expect or restore there but then with deeper laying and 18″ in the direction (you will certainly hate me for it) Would I look forward to numerous answers!
