Why don't you post directly in the comments on the site as I suggested you? (on each vehicle page the info about that vehicle, not a whole list on the movie/series page)
- it is easier for us to process
- it provides an history on the vehicle page to know why it is listed that way.
If later someone sees a vehicle listed as a different year than the comments already on the page he may think that it was missed / forgotten, not knowing that it was changed due to info that your provided here.
