Prince Rainier III is an avid collector of fine cars, and for over forty years he has built up a considerable private collection of vintage vehicles.
He has assembled and restored some 100 cars, a broad cross-section of models built by the leading manufacturers in the United States and Europe: "This is not a car museum, but a personal collection of classic cars of all ages and from all countries. Popular or prestigious, they have marked their era and I like them".
Prince Albert II has continued to embellish the private collection started by Prince Rainier III.
