I drive a Honda Civic hybrid now, but we did consider a Toyota Prius. I didn't get it because I wasn't fond of the humped-up snail shape, but now that I think about it, it's a good thing I didn't because I can never remember how to pronounce "Prius."
The word looks like "prior" to me, so I want to say it that way. To rhyme with "pious" (heh--not that we hybrid owners are ever pious) or "pry us out of this car." But it's really pronounced "Pree-us," and I cannot get that through my head.
Anyway, today I found this funny article on the name. I'm not the only one!
