Lamborghini Orange County was renown for catering to the glamorous fans of the 12-cylinder $600,000 sports cars. Its doors were padlocked Wednesday.
It sold about 10 percent of the 2,400 Lamborghinis made in the world annually. NBA stars Kobe Bryant and Dennis Rodman were among its customers.
The dealership flew in actors Eric Roberts and Luke Perry by helicopter from Los Angeles to attend a company event earlier this year. Other promotional parties have featured stars such as Elton John and Sharon Stone.
The owner of the Santa Ana-based dealership would not comment on the closure, according to The Associated Press.
Lamborghini's separate sales company in the United States said the dealer closed because of its own mistakes, not the economy.
