I remember the first time I saw a Chrysler 300 in the flesh. It was 2004. Although there was a refresh six years ago, the effect is still pretty much the same.
This is called not messing with success. There is a market for a large, Bentley-esque (if you squint) American sedan with a range of powerplants under the hood...from a six-cylinder for the rental market to a Hemi V8.
