I bought my 300 C three years ago as a "new"2006. Plan to trade it next week for a "new 2010". I'm getting the same vehicle with a few more options and AWD (I live in the Snowbelt). I've owned Cadillacs in the past and they don't have anything on the 300C. Tires were worn out at 44000, other than that, have had NO problems...never been in the shop but for routine maintenance. Gets 25 mpg on the interstate at 65mph. The fact that I'm buying another should say enough.
