Hey guys, i’m looking to buy a E280-320 cdi from 2003-2006 maybe a c class. But it’s my very first mercedes so i have no idea if there is anything i need to keep an eye out for. I live in denmark (hints the bad english) and the cars ive looked at has driven 400.000-500.000+ km (2485484-3106855miles) i know it’s alot, but ive been told its no problem for the engine, but What about the rest of the car? I know it also depends on general maintness thougout the time, but is there anything to keep a look out for, other than pure happiness?
Cheers from Mads
