2006 Mercedes-Benz C-Class C230 Sport 4dr Sedan (2.5L 6cyl 6M)
I have bought this car used, and so far I am happy. The fuel economy I have been getting is an average of 25 mpg, what is not bad considering that this is a sport car. If you drive city only that will drop badly, but on high way it is very efficient. There are only two things I disliked: 1) The fact that MB did not make the phone system standard, it is pre-wired, so you have to buy the module, which cost $600 online or $1500 at the MB dealer. 2) The seats should be fully electric and not only two ways. If you are selling a luxury car, it is expected at least that.
The sport package is a lot of fun. Very nice to drive especially on the corners.
Seats should be fully electric. Bluetooth phone module should be standard. Ipod input should be standard.
