A copy of KITT, the talking car from the Knight Rider series and dozens of other memorabilia were sold at David Hasselhoff's auction on Saturday.
The car attracted about 30 bids at an online auction and finally sold for $300,000, according to the auction's website.
The identity of the buyer has not yet been disclosed.
The auctioneer said the fully functional car, which was parked in Britain waiting for a new owner, belonged to Hasselhoff but was not used in the series.
Pieces of clothing and other belongings of Hasselhoff from Baywatch were also among the auctioned memorabilia, most of them sold for several hundreds of dollars.
The dinner offer with the star fetched only $9,000, much less than the expected price of $20,000.
Hasselhoff's fame peaked in the 1980s and 1990s when he starred as a singer in hit TV shows, and was mostly known for his song "Looking for Freedom".
The career of the 68-year-old German actor and singer has faded in the past years.
Hasselhoff promoted "The Hoff" auction on Twitter and Instagram for several weeks. In a video he shared Saturday, he claimed he will allocate a big sum of the auction's revenues for charities.
