Hello, I was in a car accident about 2 /12 weeks ago and my car got totaled. It was not my fault. A lady ran a stop sign and hit my vehicle. The car in question is my 2007 Custom Chevy Cobalt SS. It has way too many modifications such as: body kit, butterfly doors, dual-pipe exhaust system, rims, some mods to the engine and so fourth. The company I am currently dealing with is USAA. My insurance is Progressive. USAA has already taken liability for the accident and is going to send an appraiser out to appraise the car. The KBB value of my car is 13,000$. Unfortunately, I cannot find all the receipts for all the work that was put in. My question is: Is USAA responsible for the aftermarket parts that I put on the car regardless of some of the missing receipts? Are they responsible for any of the modifications to the car? If so, Is it just cash value of the parts on top of the KBB value, or where ever they get the value of the car from? Okay, people aren't answering my question. I'm not trying to claim money from my insurance. I am wanting to know if the party that is at fault if they are responsible for the aftermarket parts.
