I have not posted here in quite awhile. But I see this thread that I started way back in 04' is still going strong. I have used several of the newer codes mentioned here but my favorite is still G417900. This replaced the old "L" code that was really popular when this thread first started. The G417900 code still gives me consistantly very low rates (maybe not the absolute rock bottom in every case), free LDW cap, unlimited mileage, and never a hassle or request for ID. Just my humble educated opinion.
