Clue for #7: There was another brand with a similar name. They once made a car that was a puzzle here before. Both #7 and this other brand were named for a place, but only one was built there. Car #7 had an alliterative name. So did the maker of the other car I'm referencing.
Clue for #9. From a well-know, oft-puzzled and occasionally photo-featured brand. Its name could refer to either an attribute, or a type of energy.
