I think the 300/Magnum/chargers are a real winner. I did talk to some police in my area about the cars though and they do not like them. Most of their complaints are specific to how it works in their jobs (e.g. getting perps into the back seat), but the one relevant complaint was squeaking brakes.
What is it about Chryslers and brakes?
One of the first things I do with my new car purchases is order a full set of EBC Drilled/Slotted rotors and ceramic pads. With the heavy brake use here in the DC area they keep the heat down and work wonders for getting the best stopping out of your car.
Just remember to use shims to keep your brakes from squealing.
