I think most insurance companies specify aftermarket body parts when available unless you pay a surcharge. I pay an extra $50/year per vehicle to Nationwide for OEM parts. Most people don't even realize the repair shop isn't using OEM parts and don't think to ask. But the truth is, after market parts are usually fine and have the same fit and finish. It's very hard to tell most aftermarket parts from OEM. I just like the extra piece of mind knowing my car will remain 100% OEM in the event of an accident.
