Which engine 270 220 or 320
 

Hi I am a newbie, please help I am looking for some advice before buy a Mercedes. I want a diesel model, I am looking at a 2004 C270 CDI elegence with 28k miles on the clock, is the 270 a good engine to go for, I know the 5 cylinder has been around for a good few years. Would I be better with a 220 or 320. Any advice would be great.
