One last piece of advice would be for you to read carefully the posts about toll roads in Israel and rental car facility.
ie.
Renting from the 28 of month to the 3 of the month - 6 or 7 days later is a 2 month servie fee versus renting from the 3rd of the month to the 28th being within one month.
In addition to the monthly fee there is a per use fee.
The final bill will arrive as much as 5 or 6 months after the rental
and so on......
