No need really to have 3 BMW 507 'Touring Sport' and 21 plain 507's. They are all the same exact car with no name change during production implied in the comments. As already mentioned by user 'Alexander' in these comments "Touring Sport" was to be removed. If you agree.. otherwise TS should be added to all the rest? either way as things are it suggests there's some difference in these 3 cars. My thinking is that TS should be removed from the 3 for consistency:

Also.. I don't think this 2000 1.8 existed anywhere and anyway I see no proof. So plain 2000

...and also I've identified this

that's it for now..
