A Mercedes-Benz E300 AMG (facelifted W212). Compared to typically subtle Mercedes-Benz minor model updates, the change to the W212 in its mid-cycle facelift were relatively extensive. According to Mercedes-Benz, the mid-cycle facelift is the "most significant model revision" it had ever undertaken. Mercedes-Benz is reported to have pumped close to €1 billion into the development of the mid-cycle refresh of W212, with the amount of new features on the facelifted model is about the same that's expected from the release of an entirely new model.
Sorry for my abeyance past two weeks due to exam.
