I once saw a message from a Lambo lottery winner, I think it was in this forum thread, I don't remember how long ago it was, but it definitely happened. He then received about 3.5BTC on his freebitcoin balance and in his personal account statistics it was shown as a deposit. And about Lambo and other expensive prizes in WOF - Rolex, iPhone and Amazon gift card - these are not real prizes, but conditional designations of the winning amount, for example, Rolex is a prize of $ 10,000, iPhone a prize of $ 1,000, Amazon gift card $ 500 or something like that. And Lamborghini is a conditional name for a prize of $ 200,000
IMHO

There have already been at least 3 users from this forum who won the Lambo lottery on the freebitcoin site. This is Kryptoverdienst, who won 3.08 BTC in round 5, then soslex won 10.27 BTC in round 7, and Kingqa980 won 7.44 BTC in round 9.
As for the prizes, the terms of the Lambo lottery stated that a winner could get a physical prize, i.e. a car if desired. However, all winners obviously chose BTC, as a physical prize implies additional shipping costs and fees.
