W206 C43 AMG Disaster
My wife special ordered a W206 C43 AMG and waited ten months to take delivery. Since that time, it has been an absolute disaster. She has experienced ongoing, recurring issues with the vehicle that have required ELEVEN separate visits to two different dealers, averaging approximately every three months over the past 1.5 years and is currently at the dealer waiting on Mercedes engineers to provide permanent fix. See below the list of specific issues. After owning four Mercedes, this will be the last we will ever own.

Friend of mine got a GLC 43 for his wife (she is older and sells real estate). Three engines (yes, whole engines) in under three years (and counting). That car is never not in the shop.
