The Triumph TR7 is a sports car which was manufactured from September 1974 to October 1981 by the Specialist Division (latterly the Jaguar-Rover-Triumph division) of British Leyland in the United Kingdom. It was initially produced at the Speke, Liverpool factory, moving to Canley, Coventry in 1978 and then finally to the Rover Solihull plant in 1980. The car was launched in the United States in January 1975, with its UK home market debut in May 1976. The UK launch was delayed at least twice because of high demand for the vehicle in the US, with final sales of new TR7s continuing into 1982.
In 1980, a limited edition version of the TR7 Drophead was launched for the US market by the US importer. Called the TR7 Spider, it was available only in Maraschino Black, with reflective red striping and badging plus black interior trim. Alloy wheels and the steering wheel from the TR8 were fitted, along with a “pewter grey” carpet and grey striped upholstery. Based on an exhaustive inventory of the factory build cards at the British Heritage Motor Centre archives, it has been confirmed that 1,070 carbureted Spiders were built at the Solihull factory with an additional 548 fuel-injected (Bosch L-jetronic) Spiders built specifically for California. VIN numbers for Spiders run from 400301 to 401918 overall and for the fuel-injected version from 401374 to 401918. All the Spider-specific equipment was installed at the factory, with the exception of the radio/cassette, which was stored in the boot and installed at the port of entry.
