Arrange the data by year and format.

yes that's okay, we'll just replace those mercesdes model.

I would like you to show me what they are supposed to look like after being processed... that information will guide me in which approach to take in the code I write. Just so you know, I am not asking you what to do with those exact models, rather, I am more interested in their "structure" so I wil be able to decide on how to handle similarly "shaped" models.
