For different generations we have a "Mk" field which can be formatted differently depending on the make/model.
This is for example used for the letter+code of the VW & Audi models, for the Letter of Opel models or the mk number of the Vauxhall models.
It could be used for these, if we find a way to make that display correctly (if the Sd.Kfz. part is at the end of the model name).
