Enterprise Rent-A-Car agreed to acquire Alamo and National parent Vanguard Car Rental Group

for an undisclosed sum in a deal that is expected to close in the third or fourth quarter. According to 2005 data made public by Hertz, Alamo and National garnered 19.4 percent of the market for on-airport rentals, while Enterprise's piece was 7 percent. The addition of Enterprise would not change Alamo/National's position as the third largest at airports behind Avis/Budget and Hertz. Enterprise is strong in insurance replacement and in-town rentals.
