Since we dont exactly know how the interior looks liek lets just base it off of the infiniti Q50. I think they came a long way, usually with infiniti and Nissan interior when you pay over $40,000 expecting a nice interior. Well the previous G37 was ok but not over the top. You really have to see the wuality and desin. Mercedes pretty much has that set the interior just seems to be more updated and the leather they use seems to last longer.
