Infiniti g35 or a nissan 300zx?

which should i get? Im a 21 year old male living in houston tx. who could afford to pay the car notes for the g35 since im still living at home so i dont have major bills to pay, and i can afford to put down about 10 grand for the downpayment. Plus, thats the car i really, really, really want, or should iget the 300zx since i could probably afford to pay for it all at once and then worry about using my money for other things?
