The mice and their condos have been removed from the glove box and trunk although I am sure some essence of them remains. The cars were parked in 1991, providing the critters plenty of time to reside in unparalleled luxury. 26 years of mouse poop and pee did a number on the original owner's manual, which resided in the glove box. Fortunately, the spare tire was relatively impervious to the coating of rodent droppings.
I had the "honor" of removing the nests from the car and did not contract hanta virus, at least not yet! The car is in amazing condition under the coating of dust and is now running.
