It depends upon your agreement with your insurance company (your policy). Some insurance policies specify that we are to use only factory parts, while others specify that we can only use aftermarket or used parts. We always follow your insurance company’s guidelines. If you instruct us to use only factory parts, but your insurance policy dictates that the insurance company will only pay for aftermarket parts, we will use factory parts, but you will have to pay the difference in cost. Whatever parts we use, we guarantee all our work for as long as you own the vehicle. We will always do a top quality repair! We’ve been doing this since 1956!!
