If the Extended Range edition turns up, the car has an official NCAP result rating on their website (not just the YT video for the Mulan), and my other EV order has not yet arrived, then I will switch back to the MG4.
Given it was 'suggested' as a mid-2023 release time period, I guess you could consider it the next year's model. So current MG4 is MY22 and the Extended Range would be MY23. With whatever fixes or adjustments they decide to make after having the MG4 in the wild for a while to 'finesse' any elements of spec, build, etc.
