An article in the most recent issue of MBCA magazine The Star mentions that the sale had a number of strings attached, not the least of which is right of first refusal if it is offered for sale in the future. If I read this right, Mercedes buy-back offer is primary, even if another party were to make a higher offer. The car must be maintained exclusively by the Classic Centre on a schedule set by the Classic Center at the owner's expense, Mercedes has rights to use it for a period of days each year, etc. Sounds to me to be a whole lot like a lump sum open-end lease agreement, with the proceeds benefiting the scholarship charity.
