I share Heinz's and Howard's view.
Tesla has just issued a serious upgrade to the Model S, the first in 10 years: even so it is all power related and some aero improvements, to bring the cd down to 2.009: otherwise the body remains the same.
There is no reason for MMC to revise the CX cars until 2030.... when the EV versions will be released.
I have to say I am excited by the prospect...
