September 13, 2012  Exhibit (a)(16)

To:  Dollar Thrifty employees

Subject:  Hertz/DTAG Acquisition Update

The Dollar Thrifty and Hertz management teams have been working diligently to meet all the requirements set forth by the Federal Trade Commission in order to complete the merger by the end of 2012.  We know this period is difficult for our employees, because the companies are still separate competitors in the same industry, until the merger is completed, and there are many topics that we are unable to confirm or answer for you until the government makes their final approval and the acquisition is completed.

We understand that the acquisition will put to rest some of the uncertainty employees may have felt over the past few years, but at the same time will generate many more questions and possibly more uncertainty for the impact it may have on you personally.  Both companies are committed to keep you informed as answers to your questions are agreed to and the details are put in place, yet it is also important that we don’t provide partial answers or create confusion.  We are recording all of your questions, and will provide very specific guidance on those when we are able to give you the most complete view of the integration and how it affects you.

Please continue to submit your questions through employees.questions@dtag.com.

Frequently Asked Questions as of 9/10/2012

Will Dollar and Thrifty remain separate brands following the closing of the transaction?

·   Yes.

·   Hertz is committed to spending significant marketing and advertising dollars to grow both the Dollar and Thrifty brands, as well as the Hertz brand.

What are the next steps?

·   The majority of our time and focus is currently on fulfilling the requirements to receive approval from the Federal Trade Commission to complete the merger between Hertz and DTAG. Until the regulatory process is concluded and the transaction is complete, Hertz and Dollar Thrifty will continue to operate independently of one another.

·   DTG will work with Hertz to develop a long term integration plan that would be implemented if the proposed transaction is approved by all parties, and DTG will be involved in every step of the integration to offer guidance in the planning, organization design, growth strategies and ongoing success of Dollar Thrifty brands.

·   An Integration Team will be established closer to the acquisition and will include representatives from both companies.

What areas will be consolidated, and should I be looking for another job?

·   DTG and Hertz would hope that no one make a career decision without having a full understanding of what the companies will look like when they are merged.  It is common to want to make a decision in an uncertain time, however, the best strategy is often to continue to focus on doing the best job that you can for your customers, and for your own development.

·   There will be areas of overlapping functions, and you can imagine some of those are in Hertz’s and DTG’s headquarters offices and support areas, and DTG will work on improving efficiencies.  DTG and Hertz know there are great people working at Dollar Thrifty, as well as Hertz, and which company you currently work for will not be a factor in the decision making process.  The decisions will be made on a company-neutral basis, focused on who Hertz believes will be the best managers for the jobs that overlap.

Does Hertz plan to keep jobs in the Tulsa headquarters?

·   No decisions have been made about the operations in Tulsa. Hertz is committed to having the work done where it can operate most effectively and at the lowest possible cost.  To make decisions in this area, Hertz will conduct a comprehensive analysis of geographies to compare relevant costs and other data.

Will there be opportunities for early retirement or severance?

·   The Dollar Thrifty merger agreement has specified that Dollar Thrifty’s current severance policy will be honored at least through December 31, 2013 for any employees who are terminated without cause or due to a reduction in force.

·   Regarding early retirement opportunities, at this time it is too early in the process to provide a specific answer.

What happens immediately after the acquisition is complete?

·   For Dollar Thrifty, it will be business as usual and you won’t see much change immediately.  The Dollar Thrifty and Hertz teams will continue to analyze how to transition the companies, and as those plans are outlined Hertz and Dollar Thrifty will continue to communicate.

·   Dollar Thrifty is performing exceptionally well in a generally weak economic environment and Hertz does not want to disrupt DTG’s successful approach to the business.   Changes will be made very carefully that will improve on two key pillars of the Hertz operating strategy:  employee satisfaction and customer satisfaction.
