Try Avis Car Rental. You will have to call around to different locations in the area to find out which ones will have them. We had to call around to several places a few days ago trying to find the same thing for a friend that was in town and was taking his girlfriend out for thier anniversary. Hertz also might be a good choice as well. He was able to find a nice one at the Avis in Overland Park, KS.
