That's a euro model with the six. I'd be suspicious about the AMG package. I'd try to value it as a used six cylinder car. I'd look for rust down under and look hard at the wheel opening since it has the chrome lips on it. It's so rare it will be hard to value. I'd look at the value of a us spec v8 slc and assume its worth less or no more..
