Firstly, I am surprised mercedes are quoting MPG figures don't they know we are metric now?, or was it an american site?
Secondly, does anyone buy a car and expect it to provide the fuel consumption that the manufacturers suggest?
Theres probably a disclaimer somewhere(in a tiny font, in an obscure part of the website) stating that anything you read on the website may be incorrect or subject to change without notice!
Deffo UK site, displaying pound sterling, got the link for specs and price list, but could not get the link for the brochure..
