My new cougar has a stamp under neath the trunk that says Avis in pink lettering. I saw a 30th anniversary cougar last year that had the same stamp in the same spot. I thought it was a rental car and the company puts that stamp there for some reason. I pulled car fax and my car was never a rental it was a one owner car from a old guy and the other car I saw was never a rental. Anyone know what that stamp is and why it's there.
