My car should have broken down and stopped running many times based on how I treat it, but it hasn't. It is very reliable.
I like that it is a very forgiving car and very reliable.

Infiniti g35. Best car ever!
I love my car, it is very reliable. I haven't ever had any major issues. We purchased three 2003 in 2013 and it only had 40000 miles on it so it is running great. The leather seats are very nice, and make it just feel so much more classy. There is a hidden first aid kit in the back seat middle console which I love.

Comfortable drive
I love my 03’ G35!! This is comfort ride. However a lot of the g35 models are known for head gasket issues. I spent an entire year catching a leak. Replaced a majority of the cooling system before realizing it was the head gasket. Which is at minimum is $4k job! Listen after all of that I am still giving her 5 stars because I love driving this car! Performance is good! Gas mileage could’ve been better though.

Top rated infiniti of all time
The infiniti is the best car. It is part of the Nissan family. It is reliable and last forever. Quality is top notch and runs like your on the race track.

Owning an infiniti g35 since new, for 15 years.
My infiniti has never had a problem during the 15 years I have owned it. It has a lot of power, good handing, and it looks good. The only complaint I have is with the seat belt holders located on the top of the seats. They squeak and rub on the seat, making noises and leaving marks on the seat.

It's an amazing brand of car.
I love the power of the motor. I also like the body style of my car. It is about 15 yrs old and it runs great with all the up keep. I would buy another one just a newer model.

It is a quality built car and good on gas.
The car is good on gas mileage.I don't really like the headlights on the car. The cover of the headlights become so dull that using them is hard to see.

It is a luxury brand car and it had lasted way longer than I expected.
It is a good car. It is a luxury car and it still running. It had two previous owners and 160,000 miles on it. However due to this I had the fixed it to have it last longer. I don't like small car, but I like this one. However, next car will get will be bigger. I'm happy with this for now.

2003 Infiniti g35 - a good buy for the price.
One problem is the door can lock with the key in the ignition with the car running! City gas mileage is not great. Ride is comfortable. Stupidly they put a regular clock in the car, unable to see at night! Also there is no lock on the truck! If your key fob does not work, you cannot get in the trunk. Really bad design! There is no button in the car for opening the trunk.

It runs good and gets you from point A to point B without raising any concerns for safety
Just needs to be updated overall. Doesn't have many features I like.

This car is the Best, from driving, it's tight no play takes curves like a champ. You have the power to pull out in any traffic {will jerk your head back twice} it's got the power. Drives like you are on glass, so smooth. I am looking for a newer one at this point but it's hard to give up this one! Have had normal issues nothing big has great motor.
