I'm seriously considering buying latest 'Blue Efficiency' C class Estate with all the 'goodies' and dealer assures me C180 has plenty of power for the size of the car. Its purely for low mileage (<12k annually) social use, however, my thoughts are that for the same money say without 'Comand' option, I could actually get 220CDI 'Blue Efficiency' and have no concerns about power and achieve greater mpg and better residuals. Are there any C180 owners with views on this model.
