What rates have been given for insuring the Model S and where/what companies are being used.
Try one of these:
Geico.... around 500 every 6 months.
I just got my quote from AAA for my MS coming tomorrow for $1234/year. That's not including the annual rebate for good drivers that comes at the end of the year.
AMICA (usually rated best insurance co by Consumer Reports) charged me $975. I think the deductible was $1000.
These guys will give you a quote for CIG, Mercery, Hartford and three more that all offer OEM: Fireman's Fund, Chubb and Allied http://goo.gl/fpO6M
