cheapest, IMHO, is thrifty.com it is $12 a day and that is with their standard insurance (or that might cost an extra $10 per day), with a $500 deductible. If you wanna use your Mastercard World, you get off the deductible but add $12 a day for TP. In Israel, in the event of damage, you pay out and get it back from mastercard. Double check on your specific card to make sure you are covered. Their rates for a week are like $60-70 (not including insurance).It may be total of approx $135. If you rent and have a tourist visa (3 months) stamp in your passport, you do not pay tax (16%).
