Think this is a good rate???

Our trip is coming soon, 12/18-12/26. I have our transportation from the airport and back all lined up, but then got to thinking. After playing with the car rentals online, the lowest rate I could get was $237.53 for those dates and that was with National. That is picking the car up at 1pm and dropping off at 7:30 am.

What do you think? It's obviously more that the car service, but having a car would be nice...thoughts please.
