As usb said make sure you add in insurance cost and yearly registration tax/license fees that my go up with a newer car. You could also hold off for PiP gen 2.
Have you checked the fine print of the ad? Do you qualify for all incentives that get to the advertised price? This is a tough call. It seems to me if you're talking in strictly financial terms, you will keep the current car and wait until you need to replace it. However other intangibles may be a factor - just wanting a newer car, or reducing cash flow versus initial outlay, etc - you decide what is most important then make your decision from there.
