Hi Marius,
Due I am interested to buy one I was worried about this topic you haindicated: do a driving test to became owner of a Murciélago.
So, I was contacting the Club here in Spain, in Marbella, and they clearly tell me: NO.
Is not necessary to do a driving test here in Spain to became owner of a Lamborghini Murciélago.
The only you need is the money.
In fact, they told me Lamborghini cars are easy to drive in normal driving street coditions and they emphasize me "is not necessary to do any driving test or show any skill", the only you need is the money.
The club have a customer service which helps you to find the Lamborghini of your dreams (new or used) in any world place and they have technical service since last year (but I guess it is not a real technical service... like companies devoted to Lamborghini)
Summarizing, is not necessary to pass any test or demonstrate any skill driving the car. Almost, in Spain is not necessary. I unknown if there in USA or in other countries it is, but here is not.
Was ferrari's brand prepotency which demand to their user who desires to own certain special models to pass a driving test showing their skills.
I have understood they are not doing this test anymore due the failure of their clutches (-joke-)
I thought was necessary to quote this information about do not pass any test, because it could be of help to future users.
Thank you
