State Farm only uses OEM parts...weather it be new or used. After one major law suit the no longer write aftermarket.
I used to have state farm. After an accident claim that totalling my trans am, and 7k in receipts they dropped me. It was get dropped or not pay the invested value. There policy states that they will pay the previous 1 years worth of work performed on the car.
Switched to Nationwide, (doug reedy reynoldsburg) and will never look back. 4 license suspensions, 38 convictions, 3 totaled cars.... i pay 330 every 6 months for my truck, car, and camaro.
