Hertz has been buying less and less cars the last few years and renting/leasing cars from car companies for a period of months or miles whichever comes first. They call them turnbacks (GM and Ford mostly) If you see a GM or Ford product, maybe others, on a Hertz Sales lot more than likely it is a turnback regect. If they go over a certain mileage or if it was in a accident that been repaired they will not take the car back and hertz ends up buying it and using it longer and then selling it themselves.
