I have the 5.7L and have zero regrets. I am getting around 18.5 MPG and that's all city driving. I took a little road trip about two weeks ago and averaged 25.5 on the highway. I traded in a Lincoln MKZ with a six cylinder for this car and I am getting the same MPG as I did in the Lincoln but with the all the fun of a V8! For what it's worth, the new V6 is far beyond that of the old and is said to be a very good engine. I know some colors were affected by the earthquake in Japan but I'm not sure which ones. I'm sure someone else has more details than I do on that. The word around here seems to be that Chrysler is trying to get the 2012's out in August. Not sure if that will happen but it sounds like very few things will change for 2012. Good luck with your hunt and thanks for your service!
