Hi there's an upcoming auction happening here where i live in Australia and by chance a C43 w202 has showed up in bad condition. Because the car has been hit hard i believe the chassis frame has bent and a number of different things as well. However, as i own a 1999 c180 Merc, could i just buy this C43 for cheap and use it as a donor vehicle for my C180?

 

depends on what you want to use? If you're looking at the engine, your c180 frame would not support a v8 unless it's modified. The car wasn't designed for a heavy engine therefore the parts including struts and control arms weren't made strong enough.
