Catch your drift Mike but as Steve says,if the warranty is the one supplied by the manafacturer then it is covered.If a third party(usually an insurance company)provides a warranty I think they can(but usually don't)specify who services/repairs.The key difference is warranty on a product by manafacturer or optional warranty provided at a cost by third party. If your BMW dealer is selling nearly new cars with BMW warranty then anyone can service them.
