So far, the only difference between the 2014 Q60 and G37 coupe is the badge and I think some extra exterior paint options. It's probably better to buy a new 2013 model when prices get reduced for the newer stock.
No change really from the G37 except for the badging boys. You can just buy a G37 right now and order the Q60 badges and switch it over no one will notice the difference. unless they have changed some things over in the interior but I doubt that is the case.
Thanks for finding the ordering guide but even the ordering guide itself looks exactly the same from the G37 Coupe. The colors and all the options are the same. So no big surprise here. **** it I was hoping for the refresh.
