Yes, there is a whole car rental service building with several car rental agencies (such as National, Enterprise, Hertz, Avis, Fox, etc.) Take the AirTrain tram using the Blue Line to the Car Rental stop. It will take up to 15 minutes to get there depending on what Terminal you arrive in. The Red Tram line just goes between Terminals and the BART station.
