Well, I just bought my "next" car and it's an 06 Mustang GT. After driving the Contour for 2 years, I realized how much I missed having a Mustang. Although I haven't got to drive the 06 much yet (I'm working out of town right now), I love it so far. I loved my old fox and there will always be something about those that I love, but the 06 is light years ahead of the fox in terms of build quality and "refinement". Granted, it's not an Acura or Infiniti, but Ford is really making great strides with their latest line up.
And yes, the price tag can get just a touch out of range on the GT's, but I got mine on X plan and don't regret it at all. This summer I'll probably start throwing some basic modifcations at it, which should only make me smile more
