Same weights are listed in the '92 literature as those Tobias stated. Also, the CE is only 3.3" shorter overall, and all of it is in the wheelbase...exact same front and rear overhangs. Of note, the CE also has the same track and overall width as a 300E.
Beautiful cars. Get the M104 motor! Kinda slow without it, but goes fine if that's not your thing.
Best regards, Michael
