I would take it over the A7 for sure, probably the CLS too but I'd need to think about it. It looks good from every angle, perhaps a bit long but overall looks great inside and out. I guess I'm just not so excited about it because it's basically a 4dr 6 series nothing different. At least the CLS stands out.
That said, I'm sure I'll change my mind when I see it on the road because the 6 series doesn't look so amazing in photos but trust me it looks good on the road.
