need to know the type of damage before delving into options

straightening a frame may not be worth it as the car is essentially "unsellable",  front end damage ditto

but if it's body panels, bumpers and suspension parts - and you are determined to keep the car...

have it repaired by someone who is willing to do this kind of work at a lower cost - 

shop around - its your car

insurance repairs are often inflated from the get go and so going to the repair shop recommended by the insurer may be ill advised

for all we know the damage inflicted may be a smashed fender and a door - easily fixed for under 8 thou - by an  honest body shop
