I never understood what the percent break down on MB v. non-MB parts meant. Are we talking about the actual number of components? Are we breaking down assemblies and sub-assemblies to count screws and washers? In other words does the engine count as one part of thousands?
For all I know they broke down the percent by the weight of MB v. non-MB parts.
What I do know is that the engine, transmission, and suspension is MB. It doesn't have the cache of a MB, true, and I can't impress the neighbors, but I really don't care. This car should run reliably for a couple of hundred thousand miles. Very few Chryslers have done that.
