I like the C-class a lot.
I'd suggest looking at the C230 instead of the C220. The engine was bumped out in displacement and it made a noticeable difference, particularly in torque.
The C220 became the C230 in 1997.
One of the moderators on this site, Gillybenztech (a dealer tech), has posted that in his opinion the C230 is the most reliable Mercedes to own.
