The Southward Car Museum (www.thecarmuseum.co.nz)  houses a collection of over 350 vehicles, as well as three aircraft and various other exhibits including motorcycles, bicycles, fire engine etc. The motor museum is run by a charitable trust, incorporated in 1972. The car museum is located on Otaihanga Road, Otaihanga, just north of Paraparaumu on the Kapiti Coast of New Zealand's North Island.

The car museum is approximately an hour's drive from downtown Wellington and is situated between the North Island Main Trunk Railway to the west and State Highway 1 to the east. The  car museum's collection includes Marlene Dietrich's 1934 Cadillac Town Cabriolet, a 1915 Stutz Indianapolis race car, gull-winged Mercedes-Benz, a 1950 Cadillac "gangster special" that belonged to gansgter Mickey Cohen, and an 1895 Benz Velo, imported to New Zealand in 1900.

The car collection was the work of Sir Len Southward and his wife, Lady Vera Southward. They began collecting cars in 1956. After achieving success in business, Sir Len dedicated time to buying and restoring old cars, adding to the collection. The Southward Car Museum was opened in December 1979, and after his retirement Sir Len devoted his time to the museum.

Thecar  museum is a purpose-built building, featuring a 6000 square metre exhibition hall, engineering workshop, gift shop, and restaurant, and is set in six hectares of park-like grounds.

The museum building also includes a 474-seat theatre, and features a 1929 Wurtlitzer theatre organ, which was originally installed in the Civic Theatre in Auckland.
