Speaking of rental cars, Hertz has a Visa Infinite page too: https://www.hertz.com/rentacar/hertz...e_Benefits.xml

No Five Star for US cardholders, but there is a 15% discount and a free car class upgrade (if/when they update the expiration date on the downloadable voucher). Will be interesting to see if this actually works, but then again, there's already the "choose any car from the Gold lot" thing.
