Not sure how far on a tangent you want to go. IMHO, the 'development' story of the 3W didn't end with MMC's birthing of this vehicle.
As others have implied, IMHO, it was 80% baked upon release and at best, 90% by the end of production. The true and probably only bench testing was done by members in this group. If the story is about the 'M3W' vs. MMC, the picture is only complete by referencing this strong Forum support, the survival kits mentioned by Bunny and the 'improvements' developed by Phil Beasley (UK) and Emil Rolando (US) to keep these things on the road.
What a good post....
