help me decide pleaseeee

Going 2 buy a new car(almost new) in a few months and need some helpfull info. Spending around 25,000 but would give more if i had too. Looking for speed and a car i can upgrade with mods. Right now im looking at at 350Z's, g35 coupe, used M3 or im thinking about waiting for the new camaro. Anyone know the accurate month when it comes out and starting price?

thanks in advance
