Not my first rodeo.
Have you got the skill set to strip, remove, prep, re bond, glass, prime and paint this body? Never mind the room and time? Do you have access to a frame jig, the patience to remove the entire body, drive train and suspension? All this is a mute point if there's no insurance money to help in the costs. I estimate the damage at at least $ 10,000 - $15,000 if I was doing the work.
This was why I asked earlier if an agreed value policy was in place. Throughout my restoration, my agreed value has increased every year, just for this very reason. In the event of an accident and 'total loss' as far as Hagerty is concerned; I would at least have a good sum of cash with which to make an educated decision as to whether or not to save her.
Not everyone on here has that skill set, and when tragedy strikes, the insurance money goes pretty fast when you drop off that amount of damage at a reputable shop. He may not have the option to bring it back if he's relying on secondary parties.
Hope this isn't the case, but if that car had an agreed upon value of less than $30,000; then an adjuster will be hard pressed to justify not writing it off.
The other big issue that can arise is the potential resale hit when trying to sell a car that 's been branded as salvage. If the insurance company writes it off, and you buy it back to fix yourself, you carry the 'branded' title with you come resell time.
