I have no idea, but put in Budget and Optimum into google...

This sheds some light...

"Even value brand Budget has an upper-level tier for its most valuable corporate customers. Perfect Drive Optimum offers such benefits as being escorted from the airport gate to the rental car, says Krista Musur, Internet marketing manager. She adds that loyalty program members are the agency's most valuable customers, generally renting more often, but specifically renting more often through the company's Web site, its least-expensive distribution channel. But their value goes beyond profit. "They also tell us the most about the site and our business," she says. "We have a survey on our site. Perfect Drive customers give us feedback every day."

Though I still have no idea how one qualifies. Heck, I don't even understand the frequent renter point program with Budget. Though I did once get a pair of ski goggles from them.
