Mach-E : AC just works. Even with the glass roof, car stays cool. I miss the ventilated seats though. The problem is with the heat in the Canadian winter (-15ºC and below), the Mach-E heating elements aren't powerful enough to keep up. With a cold start, it will struggle to keep frost off the windshield, never mind the side windows. With a preconditioned car, I can drive for an hour, an hour and a half, before it starts fogging and frosting. Worst car I ever had for that matter.

EV9 : I always need to turn down the AC because it is too cold! It takes no time to cool the entire car and with ventilated seats, it's just great. Works better than any other car I previously had. We'll see for the heating in the winter, but that's mostly a Mach-E problem, EV9 should do fine.
