There were the same signs of mice in our Boxster too. We also had a small nest under the arm rest bin where the parking brake is adjusted.

I had the same thing happen. Since then, I now try to "mouse-proof" the car and garage. It seemed to work last year. I use peppermint oil in the car at places mice might frequent (supposedly mice hate peppermint oil and it doesn't smell bad). I put down several glue traps and my exterminator sprays bobcat urine in appropriae places. When he was spraying the first time, we saw several mice "getting the hell out of Dodge".
