But for the purposes of the forum, and all who read it from many different countries, if you quote in US$, it will make more sense.
All sites have a function to choose currency, and even to me, the prices quoted do not relate to anything I know. In fact it would help if you were to convert your money into US$$$, if even only on paper..
You are not travelling for months yet.....why does the car have to be decided on now? Keep looking over the following months, and who knows what a deal you may stumble upon......... in US$$$$$$
And remember Budget.com (not budget.com.au) you have to specially look for they do not give their prices to the pages like expedia. I have always had excellent deals with them (for short term rentals), especially if you click on the nationality button and change it Australian.
