Check the website daily when you have dates in mind. I find the free points are adjusted at least daily and you can cancel and re-book for the lower points option if you need to. Airport locations tend to have great deals but they do have hire fees and taxes associated with them. For instance, I ended up getting a Suburban at the FLL airport for only 600 points a day. The economy car class was more points, guess people were opting for better fuel economy. I think the Enterprise system is fair you just need to shop around and be flexible.
