I don't own a 300C but I do have a Charger which is in the same family and it is a great car. The hemi has gobs of power when you need it and to be honest with you it gets good gas mileage on the highway when it isn't needed because of the MDS system. Room inside the car is fantastic and it is very comfortable. I know I know I am talking 300C here but still the size of the two vehicles inside and out is very similar. Highly recommend it if you are considering getting into something larger.
