OK if we go back to the beginning now and revisit roow110's post. Although there were some positive comments about the proposed M3 design, some felt it was too 'compact/sub-compact' and/or SUV-ish for the M3.
If we have been following the thread the consensus seems to be that the M3 should have a longer w/b than the BMW 3-series but shorter than the MS - so about 114". Overall length similar to the BMW 3-series - possibly a bit shorter to make it easier to manage but still bigger inside.
Height around a couple of inches greater than the MS - say mid-way between average sedan and lower SUV's - 58"?
If we fiddle with roow110's picture (rather badly with a print and pen...) to incorporate these facts we end up with something like:-

which I quite like..............The wheels are TOO big (about 23"..!) but that can be rectified.
Maybe roow110 could do a decent picture along these lines?
