Having owned a 300 for many years, it's a great car with the 3.6 V6, 8 speed combo and has good hwy fuel consumption. It's one weakness is terrible headlights in all trims other than the 300C which are HID. The halogen headlights in other trims are dim and very poorly focused, poorly designed reflectors are probably the culprit. Having said that, I have never driven a 300C so cannot comment first hand on the beam quality and focus of those HIDs. I just know that they are much brighter vs the OEM halogens in other trims. Something to keep in mind in case you do a lot of night driving.
