Is anyone benefitting from the winter storms?  Yes.  The unrelenting winter is proving to be big business for auto repair businesses and insurers, who say they’re seeing a sharp increase in claims.  The State Journal-Register reports there’s a three-week wait for repairs at some body shops.  At one business, mechanics are working 12-hour shifts to keep up with demand.  Another business is changing how snow is removed from their lot to make room for more cars that need to be fixed.  Meanwhile, insurers say they’re sorting through a marked increase in claims.  Bloomington-based Country Financial says it has received more than 14,600 auto and property claims in December and January.  That’s up 30 percent from the same period last year.  A spokeswoman for Bloomington-based State Far says claims were up 21 percent in December.
