The best rate using the rate checker link you provided seems to be at $70/day but when I bid last night on PRICELINE, it offered me a $56/day rental for a convertible. I'm trying to see if I can get one lower than that by bidding closer to the dates I need one, but as of now that $56/day seems to be the only thing PRICELINE is willing to take. I assume this is likely because it is still early relative to a Feb 13th pickup date.
