I bought MS40 then reserved a X to replace our MB ML350 for our long trips. As you known X will delayed until second half 2015 or even longer and I dont want to drive MB anymore so I bought S85 for our long trips. I really really want to keep S40 then sell MB but my wife wants opposite way althought she loves Tesla too. Now we have MB ML350, MB E350 convertible, S40 and S85. The X delayed that the reason I bought S85
