This car is in the LDAR group, but the 535 is rare, if you get a diesel GT it will likely be a 530d. I do not know if you can request a certain car initially, but if you visit the garage before the rental office, you could be able to convince your way into a specific available car if you deal with a nice RA.
I rented LDAR in Berlin 6 weeks ago, I received a 528i Touring - fully equipped but thirsty at times.
