"front differential is totally destroyed, both front axles are gone, both front fenders, the hood, the a-pillars, the front crash assembly and bumper, the right front and rear doors, both front wheels, the entire front brake assembly, and the front subframe all need to be replaced."
With all that damaged, it would cost more than half the car for labor.
Im sure you can persuade the Insurance Company to total it.
Tell em it is not going to be the same. Because it is not going to be the same.
Especially when I had my fender bender just to repair small damage on fender & front bumper was over 2k+$ Once I told em about the hood they tacked on another 1k$.
Considering amount of damage done to yours I would say totalled.
I wouldnt waste anytime measuring the frame. Unless you have sentimental value over your current RA. I would just start pulling parts out, just a suggestion.
