Hi Steve
Seems that the M3W is just a marketing tool to sell proper 4/4's.
Great choice, I bought my 4/4 having initially lusted after a M3W, but the complete lack of a hood option was a deal breaker as there was no way Mrs Z would do the European trips I fancied. I liked the power of the Plus4 but chose the 4/4 with the intention of gradually upgrading it. So far I have had the engine remapped, and it will be coming back with a shortened rear axle ratio in the next week or two.
