Ok that's 2 out of 1027. its a start :-)
I can give you about another 8 chassis replacement pre 2014 M3W's out of our small Talk Morgan community, without too much research, plus a few more early cars that have been offered for sale with post 2014 chassis fitted. The TM and MTWC "known" M3W's probably number less than 200, so out of the approximately 2500 M3W's that were produced, we only "know" of under 10% at best and many of them will be post 2014 spec chassis cars. The reality is that the figures don't look quite so rosey if you look at the "known" pre 2014 cars and how many of them we know have had replacement chassis.
I assume that the other 90% of owners, that we don't know about, either have no issues with their M3W's and it's only us on TM that have problems (unlikely), they don't actually drive their M3W's and just look at them (more likely), or have just pushed them to the back of the garage (I have met a few who have done this). If you don't drive them, they will certainly not have any problems, just sitting there looking pretty. The chassis will never crack. Some of these "perfect" low mileage early cars appear for sale occasionally and can be a bargain if the potential cost is factored in.
I cannot say how many cars had replacement chassis fitted by Morgan but I can say that they perfected the replacement down to 2 men in under two days. Plenty of practise to get that proficient I would say.
Ignorance can be bliss but you have made the effort to find out about this before buying, to your credit. It is a lottery and you may get many years of trouble free use from your 2012 M3W, as many have. I would just use it and enjoy it but be aware of where they can crack and check it frequently, for your own safety. If it does crack then it can be repaired, maybe not easily or cheaply but it can be done.
