First, it is great that your husband is safe!
About insurance companies, let them know EVERY aftermarket expense you had, including window tint, decals, EVERYTHING! If you have receipts, better! If not, contact the vendors some of them may still have your order in their system.
last yr, my insurance company gave me over $20K for an 8 yr old Pontiac Solstice GXP and then mailed me a check for a little over $200 when they discovered other aftermarket parts while they were dismantling it.
Good luck and please get another SASSY CAMARO!!!
