Rented an XFAZ two weeks ago from LAX. Happy with the service and had no issues picking up or dropping off. I got a fully loaded high mileage Escalade ESV which was fun to try out but probably will try to avoid it in the future due to its large size. I saw one black X7 on return but otherwise mostly Escalades.
I did find a unicorn in the fleet which I talked to the staff about. A brand new Volvo V90 Cross Country with every option available. Apparently the only one in the whole fleet.
