Not at all for Merc, BMW or Audi, but definitely yes for Rolls Royce.
Infact, even if you want a test drive of exclusive cars like Range Rover, Rolls Royce, Lamborghini etc., they ask for your visiting cards, do a full background search on you, and then offer/decline you a test drive.
I have done it too... (P.S.: Its fun declining someone a test drive... sadistic pleasure! LOLZ)
OT but I remember an incident when I used to work in Land Rover. A guy called up from Nashik & he wanted a test drive of the Range Rover Sport. He wanted us to pick him up from the Airport & drop him to his hotel, 30 kms away from the airport! I consulted my senior & did a small check on whether he can actually buy the Sport. I called him later and said, "Sorry sir, Range Rover has stopped offering cab services for free!"
