range that I can always charge to 100% — unlike other brands that told me it was recommended to stop at 80%, which consequently cut my real range from 600 to 480 by not being able to charge to 100%. I think that's something people should know.

Stable car and generally good build quality — but I hate the Google and infotainment systems, which both seem designed to irritate the user as much as possible.
I'm looking at a Toyota B4ZX AWD when the lease on my EX40 expires. I need to be able to tow 1,500 kg, but without going broke.
