Mercedes-Benz C300d review: Is this the best C-Class ever?

This is the facelift of the latest generation Mercedes C-Class (fourth-generation to be specific). It is not just an ordinary C-Class but the C300d somehow has an AMG (performance car division of Mercedes-Benz) in its name and that is the name of its sole variant - the AMG Line. It is probably the best performing regular C-Class we have ever seen, surprisingly with an inline-four diesel engine, and also gets Mercedes-AMG treatment to its exterior. So, we took the Mercedes-Benz C300d AMG Line for a spin and here's what we thought about it.
