The W212 actually is apparently the first M-B of a different size to engage in "platform sharing" with another model. I remember reading reports where M-B said they wanted to test it out and afterward gave it the greenlight for future models. The E Coupe IS actually on the C-Chassis, completely identical, but the W212's is "based" on the W204's. The W212 is on a modified chassis that first was introduced on the W204, but not an identical chassis (obviously, as they're different sizes). - Right answer
As for the Ghost. What I'd like to know is if there are any IMPROVEMENTS to the chassis than the F01. I.e is it stiffer? Stronger? Better material build? More balanced? Etc. The F01 has a great chassis, but for $300+K I'd want "my" Ghost to have either a completely bespoke platform (I mean, much less than $300K should be enough to buy that privilege), or at the very least an extensively improved F01 chassis (which it very well may be?).
Yes again as Ghost = improved 760iL chassis.
