Pls don't be too harsh on him
"there is a connection between this automaker and Steyr but nothing like You wrote"
- as you can see he admitted a connection.
And as for Magna. Magna bought Steyr in 1998. When the is Jelcz-Steyr competition was held there was no connection at all between Magna and Steyr.
Maybe if he says "yes, Magna owns today Steyr so there's the connection" - this may have been a bit more succesful, but for solving the puzzle, it did not mean a thing.
