There will be a XEC, XECC and XESB, there IS a Mercedes C-Class Coupe, and a new one is undergoing testing now,
I very much doubt that, CLS vs E-Class E-Class wins hands down, Passat vs CC, Passat wins hands down, and so on, they are more expnsive versions of already existing cars, and most people are not that stupid.... LOL..I think that they will make an XE Coupe. Everybody else seems to be making cars like that, and I've been reading that coupe styled sedans sell better than regular sedans. SO all signs seem to point to yes.
