No experience with this problem myself, but the thing that seems to jump out to me is adding more synonyms to the page that you WANT to rank well.
So if you want the page blue_cars.html to rank well for the keyword "blue cars" then I would definitely have the phrases blue autos, blue automobiles, blue vehicles, etc., on that page as well. I wonder if including different shades of blue (cobalt, robin's egg, sky, turquoise, etc.,) would help as well?!?!?!
The obvious problem to me then is if you are trying to get a blue_cars.html page AND a blue_autos.html page to rank, that might be really difficult, because by adding synonyms to one page you will be taking away from the "uniqueness" of the other page...
