So sad to hear! The car came such a long way since you started the build.
Surprised insurance even agreed to cover 2/3 of the aftermarket parts, were you paying additional for aftermarket insruance on the parts?
When my last car got totaled (by a drunk driver with no insurance/license) I gave my insurance company (Mercury) a list of parts & receipts worth $10k+, they offered me.... $500
Good luck with the rebuild!
Any pics of how bad the damage was after the accident?
