P400 Jota
In 1970, Lamborghini development driver Bob Wallace used chassis #5084 to create a
test mule that would conform to the
FIA's Appendix J racing regulations. The car was appropriately named the Miura Jota (the pronunciation of the letter '
J' in
Spanish). Only one was ever built, which was eventually sold to a private buyer after extensive testing. In April 1971, the car crashed on the yet-unopened
ring road around the city of
Brescia, and burned to the ground.

P400 SV/J
A Miura SV/J.
Once customers heard about the Jota, they requested their own "Jota". Lamborghini could not justify the expense of building a series of Jotas, so they offered an upgraded SV model instead. This model, known as the SV/J, featured upgrades to the engine, suspension components, exterior and interior.
Of the five examples of the Miura SV/J built by the factory while the Miura was still in production, two were built new (chassis #5090 and #5100) and three were converted from existing SVs (chassis #4934, #4860 & #4990). All of these still exist. Chassis #5100 is however the only SVJ to feature the dry sump lubrication system as per the mechanics of the original Jota #5084.
One of these cars, chassis #4934,
[6], 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 he fled the country during the
Iranian Revolution, his cars were seized by the Iranian government. The SV/J was sold into Dubai in 1995. In 1997 this car was sold via a Brooks auction to
Nicolas Cage, at US$490,000, becoming the model's highest ever price sold in an auction.
[7] Cage sold the car in 2002.
A sixth SV/J was built at the Lamborghini factory between 1983 and 1987 from an unused Miura S chassis. This was made for Jean Claude Mimran, one of the Mimran brothers, the then owner of Lamborghini.

Further Miuras were subsequently upgraded to SVJ specifications (trying to imitate the real factory SVJs) by various garages of Switzerland, USA and Japan.
