If you are using VICOM VFIT for evaluation, they will most likely be able to identify if a car has been in an accident. The paint thickness is being tested and if there are any repairs done before, the paint will show inconsistency. They will also check if nuts and bolts of the different car parts have signs of removal. This is pretty much all that can be done to attempt to check if this is a car that was in an accident.
There are no other options available and insurance companies will not reveal such information to the public.
