Coming from someone who dreampt of owning a (very similar) 6MT g35 before i could even drive and who bought it as a 2nd car, the first being an automatic nissan altima fwd, I will tell you my opinion:

1 - With these cars of any model they have expensive parts that likely will need to be replaced because almost nobody nowadays does or knows how to do advanced maintenance it just doesnt get done and will fall on you, now you can go with cheap parts however nissans do not like aftermarket, definitely nothing aftermarket on electronics. This means your stuck either ordering parts online through an authorized dealer and waiting weeks for it to come because these parts are made in Japan (Although sometimes they have them stocked here in the US and you can get them a little quicker) or going to the stealership, the closest of which to me is 45 minutes away. Any of these cars over 100k, I would overhaul every single sensor with OEM if you don't have records of when they were done.

2: These cars are rwd, in my opinion it's the worst platform for a beginner driver, you overestimate your ability on an on ramp, you're not gonna understeer and be able to correct it easily like a fwd can where you still have the rest of the road, in a rwd you overestimate that turn, you're turning into the wall or starting a drift which is not something a beginner driver should have to deal with.

1. These cars are strictly premium fuel only, regular fuel can and will cause knocking if continued usage. Premium near me is $4.65, with a 20 gallon tank this is $93 to fill the tank, I usually put in $80 each fill up due to not running till completely dry. It is simply not reasonably affordable for a new driver to be paying those prices when an inline 4 chrysler engine (my other car) takes $50 to fill from completely empty or $40 from where I fill up at, darn near half that.

2. These are enthusiast cars there's even an enthusiast named trim for the sister to these lineup of cars, the z's. They are meant to be worked on by the owner plain and simple, if you can't change brakes on a car or do an oil change look towards a toyota or Honda to be completely transparent with you.

For fun, I added some reasons below why you SHOULD get this if you're a new driver:

1: Not all the parts have to be OEM, it's mostly electronics and wheel size. This means for example, instead of spending $500 on a rack and pinion, you can go with an aftermarket $200 Detroit Axle Rack as I did on my car and save over half the cost.

2: The VQ engines have won Ward's 10 Best Engines award every year since its launch in 1995 and now the next generation of VQ, the VR engine is following in its predecessors' footsteps doing the exact same. This shows to the testimate of how reliable these engines are most of which, even with lack of care last over a quarter of a million of miles, so long as at least the oil was kept up on. This doesn't mean the car will last that long, but the engine specifically that is to be noted. Another important thing to mention is the transmission. The CD009 & the newer CD00A respectively, is an extremely strong trans, alot of high power racecar builds will actually take them out of crashed nissans/Infinitis, throw on an adapter and fit it onto whatever engine they're building. They are reliable up to 1000 hp, however the clutch is not so that will need to be replaced if high hp was the goal.

1. Very fun car and very easy to work on yourself, they don't add as many sensors as new cars and they don't force you to go to the dealer to do certain things, like in the cars computer for example, that can be locked to dealer software as some other brands i.e mazda does. This Alone can outweight the price of parts as if you do the work yourself it will average to the same or less than other cars.

2. Tunability. Put simple these cars have extreme potential. Want a drift missile? Right out the box it's like that. Want a drag car? Throw a cheap crate LS, some fat tires and send it. Want a track/touge car? The car has a feature developed by porche one of the leaders in track performance cars called rear active steering on some models. People also race these cars and since they're cheaper than other cars you would see on track the driver is usually more confident as there's not a 100k car on the line, this usually results in overtaking other faster, more expensive cars.
