I added the Prius Plug In to my auto insurance when I picked it up last week. The premium is about $400 per year more than my other vehicle (a Lexus which actually cost more when purchased than my PIP basic) but the exact same coverage. I called my agent at State Farm to make sure they applied all the normal discounts (good driver, multi car, etc.). He said yes, but could not explain why the PIP was so much more than the Lexus. Just curious - is insurance for the PIP more than regular vehicles of similar cost? Anyone else experience this? Looks like I'm going to be shopping for insurance quotes.
