Thanks for the info Jim. I'll give him a buzz next week. My wife is starting to lean on me to just sell it and get a Honda. I haven't had the car 6 months yet and have had the head gasket and wire harness replaced. Now the throttle actuator and my mechanic mentions that the rear differential needs to be rebuilt. The problem is that I really like my C280. The wife says to get a Honda with 4WD and don't put any more $$ into the C280. What do you think? Time to let the Mercedes go? It is stressing me out (which is worth something).
