How common is this? (from the Times ...)

A few nights after he resigned his post as secretary of state two years ago, Colin L. Powell answered a ring at his front door. Standing outside was Prince Bandar, then Saudi Arabia’s ambassador to the United States, with a 1995 Jaguar. Mr. Powell’s wife, Alma, had once mentioned that she missed their 1995 Jaguar, which she and her husband had traded in. Prince Bandar had filed that information away, and presented the Powells that night with an identical, 10-year-old model. The Powells kept the car — a gift that the State Department said was legal — but recently traded it away.

As my friend who sent me the link put it: Is it time to review all such gifts to former and present administration officials?
