Hello everyone and it's my first time on here. I am about to order a brand new E200d (SE) factory made for November, however the dealer has a brand new E220d (SE) available immediately at around the same price. As far as I can see on the mercedes website, these cars engines are identical in CO2 emissions, fuel consumption etc except for the power output. I do not really mind the power as long as I have the lowest CO2 and best fuel economy. Any suggestions to what I should buy?
