I've a friend in LA, Calif. that recently called me to say he was riding in an '05 Prius with a friend, had a question for me. Anyways, it had a sunroof and leather right from the dealer. That means there is a company doing Prius sunroofs (sunrooves? no) in Los Angeles. And they are doing them before customers buy, so it appears as a package deal. I know this doesn't help with details of the where and how much, etc. but a sunroof is possible. Maybe do a PriusChat or Priusonline search for sunroof, I seem to recall seeing pics at one or the other site. Love my Prius!
