Economic write off.

[RG]

Hey peoples. Does anyone know what percentage of the insurance (market) value of a vehicle the repairs have to come to before the insurer will decide that a car is an economic write off. Reason I ask is that the mrs car was hit by a tree branch in the wild weather yesterday and since it is only insured for around $3300, full comp but it is a '94 Lancer, we are trying to figure out weather or not they will repair it. I haven't seen the car yet, that will happen later today, but she says that it has hit the front drivers guard and smashed the windscreen. that suggests to me that the A pillar has also copped a hit.

Any thoughts?
