Hi everyone
I have been looking around on G35driver for a while now and looking to buy my second car.
I am coming from a 09 SI so i am a complete noob in nissan/infiniti
Most likely looking at high mileage Gs (90000-130000) due to my limited funds and was wondering what should i be watching out for? besides the completeness of the body, how far can the engine run?

thank you everyone for your input
