UK Competition Commission Provisionally Clears Streetcar Acquisition

CAMBRIDGE, Massachusetts, November 18, 2010 - Today, Zipcar announced that its acquisition of Streetcar Limited has
been provisionally cleared in the United Kingdom by the Competition
Commission. The Competition Commission has reviewed the acquisition and
provisionally concluded that it does not expect the acquisition to lead to a
substantial lessening of competition in the UK.

"We are pleased with the Competition Commission's provisional findings.
This is the outcome we were hoping for at this stage and it represents an
important milestone in the regulatory review process. The companies are now a
step closer to delivering important benefits to both Zipcar and Streetcar
members, including access to more cars in more locations, a wider selection
of vehicle makes and models, and improved service levels," said Scott
Griffith, Chairman and CEO of Zipcar. "Additionally, the Streetcar members
will benefit from being a part of a global car sharing network by using their
membership in cities around the world where Zipcar already has a presence."

The Competition Commission's findings are called "provisional" as there
is now an interim period for interested parties to submit comments on the
findings before the Competition Commission makes its final decision. The
Competition Commission is expected to make its final decision on or before 24
January 2011, the statutory deadline for completion of its inquiry.
