My car was vandalized at a auto body shop, my insurance refuses to pay for my customized rims. Can I file a suit against the auto body shop?

Yes, I believe the auto body repair shop and/or its insurance company should be responsible for the vandalized damage to your customized rims while the vehicle was in the possession/control of the auto body repair shop.  In addition, if you believe the customized rims should be covered under your auto insurance, then you can also include your insurance company as another Defendant in the lawsuit against the auto body repair shop.  Good luck with this matter.
