This is a beautiful, classy car inside and out. The driving experience is great - plenty of power with the V6 3.5L engine and it really hugs the curves; Keyless entry and push button ignition is very convenient; it accomodates 4 adult passengers very comfortably with room to spare; has a large trunk; iPod/iPhone connections in the center console is a great feature - you can even play video that displays on the information display screen (only when the car is stopped though); and the sound system is impressive. It was love at first sight.
My car is a 2008 with over 115,000 miles on it and it looks and drives like a new car. I've had zero mechanical problems other than regular maintenance and the interior is in excellent condition! I can't recommend Infiniti enough. I've owned 10 cars of various makes and this is by far the best I've owned. If I had gotten a comparable BMW I doubt it would look as good as my Infiniti does at 9 years old. I love it!
The 2003 G35 is a great car. I bought the 6 speed manual and it is absolutely flawless. The clutch will take some getting used to but it is easy to learn. The car comes with more than enough horsepower (260hp) although I would have waited and got the 298hp that was offered on later year models. The car rides comfortably even with the sport suspension which I think is a must. The leather is soft and plush and all interior aspects of the vehicle make people go ahhhhhhhhhhhhhh. Trust me I get a lot of compliments on the car. There are only 2 complaints that I have about the car. One of them being that the car will lose tractions very easy in rain and snow if you are taking turns. It will stick like glue on dry pavement but one wet pavement be careful because it will come out from under you...but thats just all the horsepower at your feet. The other complaint that I have is the Infiniti G35 is supposed to be a luxury sports car...why is there plastic on the bottom portion of the car. If you buy a 2003 or 2004 I would recommend getting one with the appearance package which replaces the plastic trim with an actual "body kit". Other than that the car is great, looks sleek and is no doubt the best bang for your buck luxury model you can get. Its been 4 years and it has been in the shop 0 times. You must test drive one for yourself.
