https://www.xrentalcars.com has sometimes wow deals. Tip: choose your rental info and search, after which you click [edit] and play around with the countries, and with a bit of luck you get an excellent rate. (try: Asian countries such as India, Philippines etc, as well as an EU country, also the USA, a South American one and the UK)
