just to add to what jon says,vehicles today and for quite a few years now have design features to spread the load in the event of an impact.so what might seem localised damage will more likely have spread to further inboard and can include in your case the a pillars and front scuttle area..its all designed to prevent passenger area intrusion.i am a mechanic and have seen what seems like minor damage extend well into the car,both in front and rear collisions..for piece of mind a bodyshop is really the only way to evaluate how much unseen damage might have been suffered.
