I am not sure about renting from Jerusalem, but I am going to Israel for Sukkot as well. With my President's club status on Avis, I was able to book a car from 10/12 - 10/22 for $203 (a class F might I add) and then called them for a $50 off coupon. So all in all, I will be paying approx. $15/day including taxes for unlimited miles and a mazda 6 in Israel, which is considered a big car for Israel. I hope this helps!
