The strongest domestic manufacturers in the 1950s were Citroën and Renault who in the ten years after 1945 concentrated on different areas of the market from Peugeot. The success of the 203 was therefore a tribute both to the excellence of the product and to the absence from its sector, in its early years, of mainstream competitors. A powerful mainstream competitor appeared in 1951 with the launch of the Simca Aronde, but with the post-war economy finally beginning to experience useful growth there seems to have been ample capacity in the market for both cars. By 1955 when Panhard gained access to the Citroën dealership network, the 203 was well established in the market place and Peugeot themselves had moved beyond their one model policy. The 203 nevertheless continued to sell well till the end of the decade.
