You might also check some of the real off brands, such as Advantage, Payless, and since it is a colony of a European country, even Sixt. Check carrentals.com, autoslash.com, Orbitz, Priceline, and Kayak, and then you will really know where the cheapest deal is. Again though, your choices for full size or luxury suv's might be limited anyway.
