The Rosengart LR2 was an automobile which was built at the Neuilly plant, on the Boulevard de Dixmude.
The automobile first appeared on the market in 1928, at the same time as the precursor of the first BMW automobile which was also an Austin 7 built under licence (built in Germany). Numerous variants of the Rosengart LR2 were produced and the car remained in production at least till 1939.
The LR2 was promoted for its reliability. A production car driven by François Lecot covered 900 km (560 mi) per day for more than three and a half months until it had notched up 100,000 km (62,000 mi) without any major mishap, and in the same period an LR2 achieved a class win in 80 of the 81 sporting trials in which it participated.
