I have driven the Chrysler 300C hemi on a long trip and it really works well. I couldn't detect any change in the engine operation and it has more than enough power for me. In addition,it got better mileage than a Chrysler mini van. However, the car is not something that I would buy, even if I had the means! The styling causes problems with the view down the side and to the rear. It is also a rather large sedan.
