2004 infiniti g35 or 2005 ford mustang gt?

i am buying my first car and i cant decide between these two. i have found an g35 for $13500 and a mustang gt $14500. which of these cars should i get, and are these cars a good deal at that price. and if there is another car that is a sporty coupe and fun to drive under 15000 dollars that u guys think i should i look at, please let me know. thanks.
