id say u go for E200 ..01 model .....surely of the best around .....the s-class models 92-99 and e-class model 92-99 ...have the most reliable engines
the link which you gave...it is 02,03 .....or in other case the guy changed the front and rear lights....you wont easily know the difference then,interior is mostly same .....the shape really changed in 07 ...01,06 its all the same basically...currently having 01 C220 CDI..and 07 E320 i guess(its at other house)
C180,C200 .....diff engine capacities....doesnt realy relate to shape or interior ...
there are kind of 2 variants....CDI (diesel), KOMPRESSOR (petrol) .....for me CDI rules,the best drive with ideal consumption
as for MARK X and ACCORD ....someone said it right, you have to drive a merc to know the diff,two know why it stands apart...accord,markx,cefiro ..they realy can never be compared to a merc
