no matter when you buy pretty much anything it will be outdated in a year... I would say wait if you really want or save some $$$$ on a leftover 09 and put 6 grand into it and you will smoke maros and rustangs
or you can buy a 07 grand cherokee srt8 off of me adn smoke em stock
as like i said the 09 370z in comparrason testing beats a gt premium rustang...
