The repair shop and in limited circumstances your insurance company. Your insurance company does not accept the liability for the quality and safety of your vehicle’s repair – the repair shop does. It is up to you to choose the best collision repair shop. Speak to body shop owner or manager to voice your concerns and ask questions. Once you feel confident the shop is adequately trained and equipped to restore your vehicle to its pre-accident condition, you may then proceed. At that time, any Warranty will be held up by the collision repair shop. You have the legal right and authority to satisfy your “Due Diligence” before signing any repair order.
