2001 Toyota Camry vs. 2003 Infiniti G35?

I currently have a 2001 toyota camry with 30,000 miles. Its a 4 cylinder automatic. I am considering upgrading to a 2003 Infiniti G35 with under 40,000 miles. I just got a better job and am looking to upgrade. Can anyone tell me about reliability comparisons or general comments about either car.
