Lamborghini Miura recreation of the Jota was later undertaken by Chris Lawrence of Wymondham Engineering for Lamborghini owner Piet Pulford from the United Kingdom on chassis #3033. There are six examples of the Miura SV/J known to be built by the factory while the Miura was still in production, one was built new (chassis #5090) and five were converted from existing SVs (chassis #4934, #4860, #4892, #4990 & #5084) One of these cars, chassis #4934, was built for the Shah of Iran Mohammad Reza Pahlavi. The Shah stored this car under armed guard with another SV in Royal Palace in Tehran. After
Production car speed record speed for both runs is taken as the car's top speed. In instances where the top speed has been determined by removing the limiter, the test met these requirements, and the car is sold with the limiter on then the limited speed is accepted as meeting this requirement. For the "McLaren F1" the estimation by "Car and Driver" about the speed at the rev-limiter is used. Comparing claimed speeds of the fastest production cars in the world, especially in historical cases, is difficult as there is no standardized method for determining the top speed and no central authority to verify
