Have a XFAR booked with SIXT LAX on Dec 23 2018 to Dec 27 2018 LAX pickup, SFO drop. Have specifically requested a Escalade as it mentions its the right category, (Mercedes-Benz GLS, Volvo XC90, Cadillac Escalade) Does anyone know what my chances will be on securing this beautiful vehicle? We don't have them here in Australia and love driving them when I am in the US.
