If you're leasing and the EV gimmicky range is not an issue then get the M60. The EV will be very quick, it will lease better and can be equipped better (rear steering).
This is coming from a guy who had two 540 G30 and just got a G60 540.
I hope one fine day range/charging won't be such an inconvenience. I will then subscribe to the EV religion too, voluntarily that is without the government's "encouragement"
