I worked at Mercedes-Benz World for 2 years, and if someone went to buy an SLR, whilst the pre test drive deposit was clearing they were taken out in a C63 for a professional track driver to assess their driving ability. If they bought the car and it was deemed to be too much car for them they were given complimentary track experiences to help them drive the car safely whilst they waited for delivery,
It all stemmed from a boxer who bought an SLR and ploughed through a load of people at a pedestrian crossing. Maybe more manufacturers need to help their best clients, it will probably keep them alive long enough to buy a second car too!
