Same here, I would also take the money. A lambo looses it value very quickly, but even when taking the money in BTC there is a certain risk as you don't know what BTC price will do in the future.
If we consider the broad user base of this website and that many people are not really into crypto especially but just on this website because its gambling or event based bets and has a free element with a deposit utility etc. They arent hard core crypto and in some way that image of an object with a fixed value in their mind though its true there is always depreciation on new cars, ironically that helps raise the value of the prize to people. Its always possible BTC can go down and be the lower of the two prize options, having the fixed option especially in perception raises the certainity of the bet prize .
