Well, I watched the reviews, and I gotta say, they look nice! The S6 is downright sexy.
Tho I liked the sedans a lot, I'd go with the Avant (wagon), as we have a sedan already & I'd love to replace my X5 and get away from an SUV.
Liked that you can choose the battery size (75 or 94); display screen(s) are nice, but almost no buttons.
Functional Regen settings, good power & range options, nice interior, kicking B&O sound system.
I surprised myself. I would cross shop these against the i4e40 & M50; they are slightly more pricey than the BMWs also: 70k -100k.
