Just a question - the Blanchard Holden is a sports-racing car powered by a Holden engine. Is the "Holden" part of the name in the rules of the puzzle? Otherwise we could just reel out an endless series of XXX-Ford racing and sports cars. Or Cosworth, or Climax, or whatever.
Maybe I'm wrong here, in which case I apologise to the poster.
