FWIW: 'Police Interceptor' is one of a few terms Ford has used for police vehicles. 'Interceptors' have, as mentioned, been full sized, both 2 and 4 door (historically a great source of wheels for those trying to synthesize SAI history).
The fox body 'Special Service Package' Mustangs are still popular at the strip and the first gen 'Special Purpose' Broncos are collectables.
