I've had the car for about 2 months. My previous car was a G37 IPL, so I will mostly compare this to that and the other two cars I cross shopped this with, the BMW 440iGC/340i and Lexus GS350 F Sport. It's definitely faster than the IPL, but it doesn't feel as sporty. I can't figure out why, but I've narrowed it down to either the tires being different or because the IPL had a LSD. It just doesn't feel that great in the corners. The acceleration is really good, though. I mainly drive on the highway and it's really useful for when you have to speed up to change lanes. From what I've read, the 400HP ranking is actually underrated. But still, I actually preferred the cars I was comparing this too. I really wanted a Lexus GS, but when it came down to price, there was really no decision at all. They have some insane deals going on. The sticker on mine was $57K. The Lexus and BMW I was looking at were $59K. My monthly lease payment is $250-350 lower with the Infiniti. My payment is actually $50 lower than what it was for my IPL and this has a lot more power and technology. The gas mileage is pretty good too. I get 24mpg in Sport mode and 25 in Normal. One time I was running low on gas, so I took it easy on the pedal and I got up to 30mpg. So in conclusion, the car looks great, handles okay, has a lot of power, interior is comfortable with a good amount of space, has all the new technology, and even gets pretty good gas mileage if you don't mash the peddle. And they usually have really good deals going on, so it's great value for the money.
