Thanks.
I suspect that's because of the accent over the 's', which of course we in England can't enter into the Search as we don't have such a thing on our keyboards..
You can easily circumvent this little problem by copy the name of the car in its original language and paste it in the search box.
True, and I do sometimes.
The trouble is, the place where I sourced this puzzle had only an ordinary plain 's' at the end, so I didn't actually know it should have an 'š'!
