With Hertz’s purchase of Dollar-Thrifty, the number of major players in the rental-car industry is down to just three. Enterprise Holdings, owner of Alamo, National and Enterprise, controls 53% of the market. Following the merger, Hertz-Dollar-Thrifty will hold 23% of the market while Avis-Budget will keep its 20% share. I bet these mergers result in fewer locations, probably fewer models to choose from and possibly higher prices.
