The Allard Motor Company in London, England, built the P1. Production of the P1s ran between 1949 and 1951 amounting to only 155 automobiles. At the same time, strategic materials such as steel and aluminum were very difficult to obtain from the British Government and it was mandatory to justify export business. The Ford components made maintenance easy on the P1 in America and a great number of P1s were exported to the United States. The original sales price of the car was 1,277 British Pounds (approximately $2,000).
With a 3.5-liter standard V8 engine, the top speed was 85 mph. The P1s were successful on the racing circuit and one P1, driven by Sydney Allard, won the Monte Carlo Rally in 1949.
