Budget - BMW X5 at DCA

As I was returning a vehicle yesterday, I noticed an X5 sitting in the Budget lot. It was parked beside a Ford Expedition, I believe.
I looked online and didn't see the X5 as directly bookable.
Is it in the same class as the Expedition?
I know from the Avis board, there are X5s at some locations.
Is the X5 also now showing at Budget?

I'm not sure but i wouldn't be surprised as i know @ some locs avis/budget have merged fleets

Was it a black X5? I passed the Budget lot on the way to National this morning and saw it. :)

Ive seen X3s, G25s, 528s also. Some of them are probably one way returns as they did not show up as available either and the locations dont normally carry them.
