Insurance on our 82 Westy equals $25 a month.  This has no comp or collision
though.  But even if I add in both it wouldn't be more than $50 a month.
This is with USAA, with a multi-car discount and a  low mileage discount.
Say what you will about them as a company, but between my in-laws and us,
we've never had problem one.
