It seems to me that you're prtty good at noting those similarities between cars. which I beleive are numerous with MB cars. I think those two cars are completly different and handle the road in their own way .Ever since they came up with the multilink rear suspenssion,those cars have been very good handling they're both design from th same idea but differ in some areas (eg part numbers...) more on that after I check at work today.
