Premuim brands often dont even have any cars available for any test drives, but they still expect you to order a car.
I have to say that’s not been my experience Carl. The 3 BMW dealers within reach of me each seem to have countless cars available (combination of demonstrators, staff cars and service dept courtesy cars) and any car I have wanted to test I have been given for the whole day. Pick up around 9am and drop back by close of play. I always book well in advance though, as if you ask on the day the specific car you want to test will inevitably have been allocated to someone else.
