I went to the Hertz site, but relly found it very uninformative. I rent cars a lot, and would like to get something out of it. I am looking for benefits such as upgrades, free rentals, FF points etc. Does Hertz offer any of these things with their program? And on the site I only see mention of regular and Gold membership, where people here are talking about other levels. Can someone please give me the run down, or a good link!!

Thanks!
