interchangeability

Hi, maybe a daft question but which parts do and which parts don't fit both models. Ie are the doors the same, is the interior the same?:dk:

Just a quick question will my GL roof crossbars fit the c-class estate?...not currently at home or I would try them....if not, any suggestions as to decent crossbars for a w203 estate....I've 4 thule bike carriers to fit on them.

I am pretty sure that I have MAS sensor problem on my 1996, (W202), C230 elegance. Like all of us I hate the robbers at the dealerships and cannot bring myself to part with 200 - 400 pounds. I think that I need part no. 940948. However I have found new sensors on ebay, (unfortunately no pics)...
