Whatever yu do yu have to get these mice out of there fast because they will start multiplying and start urinating and defacating all over the inside of car.Then yu will also start getting a stink like yu can't believe. You will not be able to drive the car anymore. I Had this happen to an old Chevy I own and I had to tear out the WHOLE interior of the car to get the stink & mice out. Good luck. Why not ask an exterminator for suggestions ?
