if I have a car titled in Michigan and have a accident in Il

insurace adjuster sent out to look at car. We are Michigan residents and the car is titled in Michigan however the car was involved in deer accident in Illinois. Not sure if I can keep the car and if so is it a salvage title? The oil pan and bumper need repair. They say maybe engine. but we do not think so. Just really blows us away that they are totaling this vehicle. The damage is not that bad. Maybe because it is a Lincoln? by the way it is a 2005.any help?
