I've owned a lot of cars over the years, and I must say that finding a high performance sports sedan with 4 doors and usable rear seats (for children and small adults) is not an easy task. Up until I owned this G37x I thought BMW and Audi were the only real options. But daily commuting during Canadian winters with rear wheel drive vehicles is not much fun. The Infiniti G37x is great on snow with its all-wheel drive traction (you can even turn on "snow mode" for greater safety on snow), moves as quick and is as responsive as many cars costing much more, and perhaps most importantly - it is FUN to drive! Not only the fact that it does 0 - 100 km in just under 5 seconds makes it fun. It is responsive, well laid out, extremely reliable and well built, and technologically advanced. And after I while, I found myself even really liking how it looks! Go figure.
