As for Avis, I think Merjerz of Seeking Alpha puts it well when saying, “Avis will, post-acquisition

The common factor between the two companies is they offer use of vehicles for a temporary amount of time. Avis provides customers rental cars at daily rates. Zipcar allows individuals to pay per hour of car usage.
The difference is the corporate company, Avis, is the profiteer in their situation, whereas Zipcar is a car sharing program in which the money makers are the individuals across the US who rent out their car.
Some may say Zipcar caved because money talks, as Avis bought them out at just under $500 million. toronto car rentals But it's also no secret Zipcar has been suffering since their inception toronto car rentals in 2000, and was indebted approximately $500 million. Not necessarily a win for Zipcar, but definitely a smart move to sell before assuming further toronto car rentals debt.
As for Avis, I think Merjerz of Seeking Alpha puts it well when saying, "Avis will, post-acquisition, be able to offer a full range of car rental services, and will have access to Zip s loyal customers and fleet. Apparently, Avis expertise in fleet financing can make Zipcar a whole lot more efficient and Avis-Zipcar can better meet Zipcar s demand than it could on its own." Agreeably, if this proves true, the point goes to Avis for making an exceptional business decision.
It definitely appears fewer people are purchasing cars these days, and there is demand as well as a large niche of consumers that benefit from car sharing programs. While a great concept for consumers, Zipcar just wasn't a successful business on its own. They gave it a good run, however, and hopefully the merge of the two won't mean a loss of Zipcar's user and earth-friendly model.
