2008 Mercedes-Benz C300 Reviews

Love the car. 52,000 miles and rear brakes are just needing replacement. Minor issues with maintenance warning message that was solved by replacing sensor in driver's seat belt buckle, otherwise never a problem. Only complaint to this "luxury sports" vehicle is wishing for a bit more than stock 228 HP. Am trading for CPO 2103 to solve that issue.
Wish I had bought a Ford. This thing is never in working order. Never out of the shop. Now having check engine lights constantly. Dealership charges $121.00 to do what O'Reilly's does for free. Every day I pray a Ford drops in my lap.
Wonderful car not one single problem. All I have done is the regular maintenace.
