The M3W services solution (I expect) is not "cheap" but it will be far more reasonable that the MMC chassis change. Assuming that a pre 2014 M3W cars value will be reduced by the possibility of an expensive MMC chassis change for many owners who would not look further, there could be a bargain for the more capable potential owner. With this repair (or similar) it, could still be a relative bargain with the assurance that it will probably last for many years with an increase in value and saleability once modified.
There seem to be quite a lot of early cars available at the moment with very low mileages. Possibly these owners have hardly used their cars for more than a short run out in the Summer and will be worried by the idea that they may require a costly MMC chassis change at some point. They could be very keen to part with their potentially troublesome M3W's for a more modest price?
I think for the more mechanically competent (potential) owner, the market could be moving towards them. For those owners who take their early M3W to the dealer for everything and just put petrol in them, maybe not so good. So I agree PaulV, a potential big hit for some owners but maybe an opportunity for some who have always fancied a M3W but they have been too expensive.
