Over the years, museum officials have said that the car has gone through six owners.
It was first bought new by Lord Victor Rothschild of the Rothschild banking family in 1936.
"I think a lot of people point to this and say it was the most sophisticated, technological, stylistic, car of its age built in extremely limited numbers for the aristocracy," described museum curator Andrew Reilly.
Only a couple of the cars remain today, and they're in collections were they'll virtually never be sold.
The Bugati on display in Oxnard is currently owned by an anonymous owner and is considered priceless.
