Great all rounder, surprisingly spacious cabin. Rapid and refined. Not quiet enough space in the boot for a bike, could use more ground clearance.

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.
