Enterprise Rent-A-Car is getting in the shuttle business. The St. Louis-based auto rental service in September launched its Rideshare vanpool program designed to — what else? — beat Washington traffic.

The program grew out of the U.S. military’s transfer of 5,000 employees and servicemen and women from Alexandria to Fort Meade in Maryland, as part of the government’s base realignment and closure process, known as BRAC. The government approached Enterprise about providing vans so its employees did not have to drive individually.

Enterprise covers the insurance, maintenance, Wi-Fi and other costs. In return, the users pay a flat fee, which tops out at $230 a month.

“It’s taking cars off the road, and that’s good for everybody,” said Michelle Bosch , vice president for Enterprise’s Washington D.C. area operations, based in Rockville.

Bosch would not say how many vans Enterprise is supplying, but she hopes it’s going to be a lot more very soon.

Investing in the government

Halifax Group, the District-based mid-market private equity firm led by investment veteran David W. Dupree, has invested in McLean-based XL Associates, which helps the federal government buy goods and services, as well as helping manage government programs.

In addition to investing in XL, Halifax is to assist the company’s management on strategic and tactical decisions.

Founded in 1989 by chief executive Lloyd M. Mustin II, XL employs more than 200 at its Tysons Corner headquarters.

“Lloyd has done a great job of building this company,” said Scott Plumridge, a principal at Halifax and chairman of XL. “ We are delighted to join with him to provide additional resources for XL’s continued growth.”

The Halifax Group is a private equity firm that invests and helps manage lower- and middle-market businesses specializing in health and wellness, infrastructure, business and government services, and franchising. In addition to its Washington headquarters, the firm has offices in Dallas and in Raleigh, N.C.

Halifax was founded by Dupree, TPG’s David Bonderman, Thomas J. Barrack of Colony Capital and William L. Rogers.
