The two are very different driving experiences.
Just like SBM I have had both.
Loved my M3W - and would love another - if I had a double garage or a rented a second garage.
When I bought my 4/4 it was clear that it was a much more comfortable drive, more useable,more weather friendly with the side screens,hood and heater etc.Better on longer trips.
So there you are - not much help I guess?
No doubt the 4/4 would IMO be the better choice.
This is not to offend my many M3W mates!!
Very same experience. Still owning my M3W but using it not that much any more while the 4/4 runs 10.000km a year
