Louis Vannod of Neuilly (Seine-Saint-Denis) and Puteaux began building sidecars in the 1920s
In 1958 they displayed an unusual microcar with three seats at the Paris Salon. It had four wheels in rhomboid (or "diamond") pattern - one at the front, one at the rear, and two in the middle. Both the front and rear wheels were steerable. The driver sat in front, two passengers in the rear.
