i am selling my e-class. i am particularly intrested in a mint condition 4 cylinder C220.i have a choice between a 1998 C280 with 128K or a 1996 C220 with 99,000. i chose the C220 because of the low miles and slightly better gas mileage.but i would like to get an oppinion from all the C-class owners out there,which is a better choice?is there a huge difference power wise between 4 cylinder and the 6 cylinder, is the 4 cylinder gutless compared to the 2.8 liter v6?
