- Yes, I think so, since American ones didn't have C as part of the model name
- Yes, personally I haven't (yet?) met in my research an EU model not built in Austria, haven't checked RHD/UK ones though because they don't pull the VIN, but I think we can do all "made for EU" ones made in Austria by default unless proven otherwise?
- Russian ones very often are grey import NA models, so I think those are to check one by one to split EU from NA models.
