So can you answer these questions for me:
Was the W210 the first MB to be completely CAD modeled? If so what CAD platform did they use? CATIA?
And was it the first production MB to be fully CAN bus for body as well as engine (as opposed to the last 124s that just used it for engine management?)

Or was the W140 the first for these now common place attributes?
