Still good until Dec 15!! Free signup and 500 points! ONE MORE DAY!!
2 steps; Sign up for Hertz #1 Club then get the free upgrade to Gold.
You can use this in USA or Europe, don’t think it includes Israel officially.
The free day can be a one day rental which can cost you $0 or some fees if not in NY. It can be part of a longer rental too.
I think the fee is a one time signup fee and not annual. CMIIAW.
The points always seem to come in slowly, at least when I rent in Israel. They are added to my account even when the Hertz location here does not add my Hertz #1 number (I think).
