This continued until 1955, after which they concentrated on cars based on pre-war DKW designs. BMW began building cars in Bavaria in 1952 with the BMW 501 luxury saloon. Sales of their luxury saloons were too small to be profitable, so BMW supplemented this with building Isettas under licence. Slow sales of luxury cars and small profit margins from microcars caused the BMW board to consider selling the operation to Daimler-Benz. However, Herbert Quandt was convinced to purchase a controlling interest in BMW and to invest in its future.
