I rent the garage across from my home to keep my C4S at .After going to Maldives and Hong Kong for vacation I returned home with thoughts of spring . Brought car to dealer to have summer tires mounted and they discovered a nest in the pollen filter . While the car jockey was bringing my car to front of dealership I asked mechanic to show me where the pollen filter is on the car he was working on . It is located in "front" of the glove box accessed thru the front compartment under plastic molding . Sure enough he opens it up and lo and behold finds another mouse nest . Now I have to figure which other car goes to my neighbors garage !!
