O well. Volvo and Mazda are still property of Ford Motor Company 
Not for long. On 23rd Dec 09, Ford announced the sale of the car division of Volvo (surprisingly named Volvo Cars, which was the only part Ford owned) to the Chinese Geely Automotbile. The move is expected to take place this year.
Also, Mazda aren't technically owned by Ford. They have a partnership. Ford own an, I think, 6.6% stake in Mazda, though once has a 33.9% controlling interest stake.
