If they're cars, you have two Prius cars... right?

"Two Prius automobiles" is more euphonious to my ear. ;)

Support the troops:  Bring them home ASAP.

I like the solution somebody else came up with: Prius cars.

I hope I find all of my source material again...

Toyota officials have said that Prius is used singular or plural,
similar to the like of sheep or fish or deer.

The Latin root of "prius" is "prior," which is a 3rd declension
comparitive adjective.  "Prius" is the 3rd declension neuter nomitive/
accusitive form, so the plural of "prius" is either "priora" (neuter)
or "priores" (m/f).  Latin 3rd declension adjectives in the nominative/
accusitive form (such as "prius") can also be a comparitive adverb,
which have no plural.

However, many people are much more used to the usual pluralization of
2nd declension nouns, where -us is changed to -i.  See:  cactus ->
cacti, fungus -> fungi.  Hence, the common usage of the plural of
Prius to be "Prii."  But, not every word follows in that fashion...
For example, the correct plural of octopus is octopuses, although some
still like to use octopi.  (Same goes for hippopotamus ->
hippopotamuses (and not hippopotami).)
(BTW: for Latin 4th declension nouns ending in -us, their plual is
also -us (long u)...)

Do note that "prius" is not a verb, as Toyota claims ("to go before"),
and actually translates to before, formerly...
(http://toyota.custhelp.com/  (Toyota FAQ site) and search for "model

Following regular English pluralization rules, the plural of "Prius"
would be "Priuses."

Some also believe that "Prius" is a proper name/trademark, and so
should be used as an adjective.  One Prius car, two Prius cars, one
Prius tire, four Prius tires.  Like SPAM luncheon meat or LEGO blocks
or Scotch cellophane tape.

Whatever plural form you choose, we can usually figure out what you
mean.  Everyone seems to have their favorite version...
