Hello, I know about all of the three cars above and I can't pick one between them. I am in the market to least a new car next month and I need to chose between these three cars. Which one would you pick and why? All of them 2007 or 2008

Well, No BMW will ever be recommended by me. It is a worthless peice of junk that is overpriced and unreliable.
Since I got that off of my chest, The Nissan 350Z is a great choice, but has a very stiff suspension, so it is very hard on turns.
The G37 is an all-around sportscar. With curvy lines and cheetah-like agileness, plus speed and beautiful aerodynamics combined with supreme fuel effieiency, the G37 is a #1 pick.

Best of Luck.
