Thanks for all the input, guys. I'm reading and processing everything.
Yeah, the more I think about it, the more I feel like I would be happier with another luxury performance sedan of some kind... been thinking about the S4 now if I decide I can't go without buying a car until the ATS-V hits.
I love a lot about the new IS. The styling is *really* growing on me, and I hear great things, but it's still just too similar to the car I drove for the last eight years, and I feel like I should get something new. That, plus, I kind of want to get a standard transmission this time around.
Still, I do like the Mustang, and I think I could get a great price on a 2014... Bah, why did that ******* have to take out my car and make me make this impossible decision.
