If I pick up my car and it has anything more than an extra 5 miles on it, I raise hell and tear them a new one. I picked up my car once and it had an extra 20 miles out of it. I raised such a stink that the manager took my invoice and marked it as paid in full just to get me out of there. He wrote off about $200 in charges.
