What yr? I am also looking at Q50s. Would appreciate any other opinions on the test drive.
Inside the interior is def updated and its easy to use the dual screens really makes it look modern. The technology is great in it too second to almost none. I didn't like some of the carbon fiber interior in the one I tested it looked cheap. I would go with the wood grain interior. I also think that I absolutely loved the front end of the car it looked aggressive and the daytime headlights looked great. The cupholders also seemed small. The console armrest storage feel small as hell too. Backseat felt tiny too smaller than my g35. The trunk is also smaller in the q50. I think they made the front seats in the q50 larger and the car shorter overall when I was looking at the dimensions and how small the back seat is. Bass sounds good for hip hop r and b songs. Also no inifiniti clock and some don't come with a spare tire

As for the engine your probably getting the best v6 without forced induction (turbo or supercharged). You get 330 hp which is hard to find for most comparable v6's. The engine has a nice exhaust even stock and it goes when you step on it. It doesn't feel as fast as fun as the g37 or g35 though. The car handles pretty good too like most smaller import cars it goes right where you want it to.
