Hi guys, I guess its totally irrelevant to Morgan, but i think I've just discovered that a giant like Mercedes has made a simple but unforgivable mistake!!

One of my friends was commenting how much better his E 250CDI saloon auto compares to C250CDI estate auto in terms of fuel consumptions. He's picking up his new E250CDI in Sept.
I didn't believe him, so he went on the merc site click on edition 125 and downloaded E class price list, and indeed, it was achieving better mpg figures than C class!
E class 45.6 urban, 67.3 extra urban and 57.6combined, which incidentally exactly same figures as E220 CDI !!!
C class 44.1 urban, 62.8 extra urban and 54.3combined

BUT !! When I downloaded E class ebrochure, the figures are completely different?!

E class 36.2 urban, 64.2 extra urban and 48.7combined, which are also exactly the same figures for E220CDI !!!

Hope I am not confusing anybody here? But which one is correct?
Unless I've made a mistake somewhere, an oversight like this shouldn't happened to a giant like Mercedes.
And surely Mercedes must risk having their orders being cancelled or sued by buyer whom bought the car based on first set of figures(assuming its incorrect)
