I have just found this quiz - closing date 30 April so still plenty of time.
It says that all answers are forms of transport but the headings are Manufacturer and Product/service and the clues are advertising slogans - Am I missing something or is there an error?
My sheet doesn't mention transport, just that all answers relate to TV adverts some current and some much older. I think perhaps you have an early prototype which has been corrected later.
