Oh no! At least your husband is OK.
As for the insurance company, make sure you let them know about all of the aftermarket parts you had installed, including paint work. If you can find your receipts for all of the work you had done, give them a copy. You should be reimbursed for all of the custom work you had done since their initial estimate will likely only be based on a 5 year old stock Camaro.
Time to start planning for a 6th gen...wasn't ordering supposed to start around mid-August?
