Hi, I am currently looking at buying my first Mercedes. I am specifically looking at an Estate C Class. It will be a fresh used car - 07 or 08. I have seen a few that are very appealing, but having read reviews am seeking some advice from the people who matter - Mercedes drivers! I have seen a C320 CDI Avantgarde SE and also a C220 CDI Elegance SE Auto. Reviews online seem to point at these models being plagued by electrical issues, and also I have read some comments in other forums about the gears going and £4000+ repair bills etc. I was wondering if anybody could share any knowledge about the world of the C class estate - does it happen to be a problematic car? Any advice would be very welcome. Thank you.
