I think the biggest downside to this is, the Q8 is here, its new, shares a platform with the Urus we ALL dream of owning and has a lot to offer... great pricing being one of them.
Seen a few already at my condo and they're impressive. X7 will however will really appeal to the Lexus LX/Mercedes GL/Infiniti QX80/crowd. For everyone else who doesn't need all that space its... Q8 all day.
