UK channel ITV's Formula 1 coverage about a week ago (19 March race) the presenter went out to the parking lot to see how the F1 drivers had arrived for the race. Schumacher and the Ferrari garrage had a pair of black QPs sitting in their lot. McLaren drivers obviously arrived in a pair of Mercs (probably S-class). This was not a planned promotion, as some of the garages had some ugly local rental (?) cars. It was clear which of the garages have "no expenses spared" policy.
