You are a little early yet to find the deals. I usually start about two months before my trip. Car rentals, to me, are the biggest pain of the planning process because it's like voodoo finding the cheapest deal, as they seem to change hourly and dramatically depending on what code you use. To take some of the sting out of it....I find a rate I can live with, that I can cancel, and book that, then try to find better deals. My go to sites are hotwire if I am going to priceline something at the airport, (check hotwire's price, then bid lower on priceline), and carrentalsavers.com. Seems those two places have produced the best results for us. Good luck!
