 After owning this car for two years and driving it 15,000 miles per year, I have to say that I am quite disappointed. It’s a very beautiful looking car and has stood the tests of time very well, and hasn’t needed anything yet. Granted that mine has very low mileage for its age, I can always count on it taking me where I need to be without fail. But the driving experience is lacking in so many areas. Compared to other cars on the market, it feels very “amateurish”. Kind of reminds me of Kia cars during that initial phase when they were trying to make the brand more appealing to consumers but still weren’t tuning the driving dynamics right. The 2010+ G37 coupes and sedans are better vehicles, but as for the 2007-2008 G35 sedan, there were numerous kinks that had to be worked out. The car just doesn’t feel confidence-inspiring. The whole thing is just too unpredictable and I never feel like I have proper control over the vehicle. It’s stubborn in the way it behaves on the road and the vehicle never listens to driver inputs. The thing that probably bugs me the most about the car is the transmission. The 5-speed automatic is counterintuitive, sloppy shifting, has a tendency to hunt for gears, and rarely puts you in the correct gear required for the situation. I guess I could have went for the manual but my options were limited at the time of purchase. The gears are all spaced very close together and it always shifts too early, cutting off power and denying me a large reserve of the advertised 306 horses. In stop-and-go traffic, the transmission shifts through its entire gearset during the 10 feet you’ve moved up in traffic and annoyingly holds the gears long after you’ve let off the accelerator, like you’re “stuck” in the gear. On the highway it revs at over 3,000 RPM because of the tight spacing between all the gears, making you think you were driving a 3-speed automatic. The shifting can also get pretty violent which makes driving this car a headache. Another thing that bugs me is the engine performance. Doesn’t have a linear or predictable torque curve. It’s very soft on low-end torque and needs to be revved out a great deal to keep up with other cars on the road. Engine is very loud and course sounding and because of the sloppy powerband it’s not really so much of a joy to ring out either. Most mainstream cars have more smooth, predictable acceleration and meaty grunt off the line. G35 does not have that and other cars on the road will be going faster from stop light to stop light than you. Often times I find myself missing that smooth, seamless, meaty, refined feel that my old Volkswagen had even though that car had a fraction of the horsepower. The steering feels artificially heavy, like they tried to go after BMW’s chunky/hefty steering feel but instead they put effort over feedback. Steering doesn’t feel predictable or communicative..just simply difficult to turn which hampers the maneuverability. Doesn’t have a good on-center feel and the steering doesn’t always give you a good idea of what the front tires are doing. Turning radius could definitely be better. The brakes are soft and don’t provide much confidence or linear stopping power. They feel like Sentra brakes...or maybe even a step below that. I’ve tested the brakes and the car the stopping distance is very long compared to other cars I’ve had in the past. You need to keep a big distance from other cars in front of you because the brakes probably won’t save you in a panic situation, which I find somewhat unacceptable in any modern day vehicle, especially a sport sedan. The cornering abilities are disappointing. It feels very heavy in the corners and makes you (along with your loose items in the vehicle) feel like you’re being sucked into a vortex around a slight bend in the road. After exiting the turn and getting back on the gas, literally 99% of the time the transmission won’t put you in the correct gear to propel the vehicle back up to speed.The car just drives very amateurish. While everything operates as it should going down the road, the car behaves very stubbornly and leaves much to be desired. On top of everything, the gas mileage will empty your pockets. While the vehicle has made it to 60,000 miles, I could see it needing transmission/drivetrain and suspension repairs in the future. These components of the vehicle simply feel very low-rent feel to them and I don’t see them standing the tests of time. Material quality and ergonomics are also seriously lacking. I’ve seen car interiors from the ‘90s hold up better. Storage solutions are lacking and the armrests are practically useless. My advice if buying this car is don’t be fooled by the advertised 306 horses. The car certainly doesn’t feel like it was built properly for that kind of power, and you rarely ever get to use them. Maybe skip the “X” and go for the RWD “S” model with the manual and the active 4 wheel steering...
