I do believe the M3W will continue to sell in low volumes.
There is still really nothing on the market to rival it!
BUT IF I bought one I would have to take all the E4 bits off !!!
I agree. The challenge is that at some point everyone who wants one (and can afford one at the relatively stable price they achieve) will have one. Unless the model moves on a lot then the demand for new drops off. This certainly happened with Lotus Elise's/Exiges, and Lotus tried hard to differentiate across the models and model years.
