Exhibit 99.2

Subject: Accelerating the revolution!

To: all employees

I am writing to share some very exciting news about our company. Today, we are announcing that Zipcar has entered into an agreement to be acquired by the leading global car rental operator, Avis Budget Group (ABG). Both boards have approved the deal; however, it is still subject to approval by our shareholders and regulators as required. Our best estimate is that the transaction will close in the spring of 2013. We will be holding a webcast town meeting today, January 2^nd at 11 am EST, where we will elaborate on this announcement and do our best to address your initial questions. We kindly ask you to submit any questions you have in advance - please send them to dealquestions@zipcar.com.

Though it came together very recently, this transaction is a game-changing validation of the global potential of the car sharing category, and a huge win for Zipcar. We believe the combination of Zipcar and ABG will accelerate our ability to expand our category-leading, next generation, on-demand mobility solution to consumers and businesses and that Zipcar will be even better positioned to deliver on our mission of enabling simple, efficient and responsible transportation solutions on a global scale.

For our members, I believe strongly that our service will improve as a result of this transaction. We expect to be able to offer more vehicles to more members in more parts of the world, to meet members’ requests for continued innovation in the user experience, offer new flexible and easy access membership plans, and better meet the needs for vehicle availability during periods of peak demand.

For our employees, I believe that our best days are ahead. Zipcar will continue to operate as an innovative stand-alone operation with a global headquarters in Boston. Our new partner understands and fully supports the importance of our values and culture as well as our brand, our technology and our commitment to deliver the market-leading user experience. With the backing of ABG, their commitment to helping us grow and lead the category, and their global footprint and shared passion for generating promoters, there will be significant opportunity, in some cases more opportunity, for personal and professional growth.

While we can expect some changes as a result of coming together with ABG, there are some things that won’t change, most importantly our ambitious goal to revolutionize personal mobility across the globe.

This transaction is already generating interest from the media and other third parties, and it is important for Zipcar to continue to speak with one voice. If you receive any inquiries or questions from the media or others outside of Zipcar, please refer them to Karen Drake at 617-336-4323 or kdrake@zipcar.com.

I truly believe that by combining Zipcar’s expertise in on-demand mobility with Avis Budget Group’s expertise in global fleet operations and vast global network, we will be able to accelerate the revolution we began in personal mobility. Buckle your seatbelt!

All my best,

Scott
