I wouldn't rush into something just because the car is a good deal. I did that in 2008 with a Crossfire when Chrysler was literally blowing them out the door. It was decent enough, but I got tired of driving it before to long. What do you like about about your A5 and what don't you like about it? If your answer is, I like the way the car drives but wished it had more power, then I think you should wait for a '15. If OTOH, you think the A5 is way too soft, too civilized, underpowered, and you miss the old mustang that you used to own, then I think you should get a '14.
