SL600 production stopped – backgrounds known?

Hello municipality, I actually wanted to buy 4 cylinders in the course of this or the next season and I have now found that the 600er is no longer in the official sales program. Does someone know the background for this and is, what could be much more interesting by this, to expect that the fall in value turns around rather or at least stagnates? Will it perhaps become a classic, since the sales numbers were not riisig anyway. Is possibly with the “R231” who wants to repel his 230/12 possibly? Offers to me Greetings Achim H.
