The problem to fixing your car is only money. Money says it probably won't be fixed. It doesn't take much to do 5k in damage any more with the expense of some systems.
Although most insurance companies give the benefit of retail costs for the cars value (in a wholesale world), they won't spend more than 75% of that value to repair. This is mostly due to the long term risk of both the repaired car and the long term risk of unseen damage.
