Hertz - Any Vans to rent from Hertz at FRA?

I used the www.hertz.de - and it appears that they do not rent minivans or anything that carries more than 5 adults - am I doing something wrong in my search, or is this location limited to cars?

Also, will our U.S. Gold Club membership be of any use to us in Germany?

The DUS thread has some van information; I have seen/been offered/declined VW vans at FRA and MUC in past.
