Last year got 10% of the value of my MB in diminished value after a
rear end collision.  ($2,250).  My own insurance company (uninsured
motorists claim)

Three years before, got $3k from State Farm when one of their insured
members hit my Volvo wagon.

Most insurance companies will send yo a form if you ask for it...but
will not 'advertise' the fact.

But --- the likelihood of getting such a claim is much lower if the
car has already been in an accident.
