What is the best price?

I live in Scottsdale, Arizona and am very new to buying a car as I am 19 years old. I am going with my father to the dealership as the car will be under his name so I get get the lowest APR and then pay him monthly what I owe. I am going to purchase the 370z touring model with sports package and automatic transmission, no navigation. I am wondering what the best deal I could hope for or a great deal that would be respectable on both ends OTD tax title and license included. I plan on putting 15k down on the car and financing the rest over 60 months. Any suggestions. I have looked over invoice pricing but would like to know everyone's opinion. Any plans or suggestions as going about this would be greatly appreciated. Thanks!
