Wow, I guess I never really how awesome the Q50 is until I drove the 2013 G37 after 3 weeks of driving my Q50. Holy cow, night and day difference. Infiniti has my Q50 right now looking at the inTouch freezing and other issues, and I currently have a loaner G37. There is no comparison between these 2 cars. Nothing wrong with the G37, but it is definitely dated inside (and out). The most immediate difference I noticed is how loud everything is in the G37 (road noise, engine, etc) and how old the interior looks. The quality of the materials is extremely improved too.
