What is the scope of an inventory search of a vehicle impounded by police?

Appellant's notice of appeal stated an intent to challenge the denial of his motion to suppress. An inventory search of a vehicle impounded by police is a well-recognized exception to the search warrant requirement because it serves "to protect an owner's property while it is in the custody of the police, to insure against claims of lost, stolen, or vandalized property, and to guard the police from danger." (Colorado v. Bertine (1987) 479 U.S. 367, 372; Florida v. Wells (1990) 495 U.S. 1, 4.) The police have a legitimate interest in taking an inventory of the contents, including closed containers, in a vehicle they legally impound. (People v. Williams (1999) 20 Cal.4th 119, 126.) Appellant has not shown the warrantless search did not come within an exception to the warrant requirement because the owner of the vehicle was located before the vehicle was impounded.
