Often callled the most beautiful car in the world this one off Hispano-Suiza Dubonnet Xenia has a very interesting history.
Owned and built by Andrea Dubonnet on a Hispano-Suiza chassis and running gear, the body was designed by Jean Andreau and was the first car ever to have a curved windscreen.
Andea Dubonnet was a brilliant engineer known in particular for his independant suspension and brake designs, and a WW1 flying ace. He built this car in memory of his first wife Xenia who died young, his second wife wanted the car gone so he hid it in a garage close by having told her he sold it. During WW2 the car was again hidden to prevent the Germans from stealing it.
This is a fascinating must see video, and listen to that exhaust it matches the car.
