I also fancy a M3W, but i'd only have one alongside my Aero.. never instead of.
It's a fantastic toy, but it really is a toy for using a few times in the year when sunny weather is guaranteed in my books. It'll put a smile on your face like nothing else for those shorter summers journeys.
However for me unless you are fortunate enough to be able to afford both, then I would imagine single ownership would wipe that smile off your face fairly quickly if you intend to use it a lot.
