The Imperial had an unusual distinction for 1981 as it was offered with an optional special edition named after a celebrity. The Imperial "fs" was a rare example of automotive history, as it was one of only a handful of regular production cars bearing a celebrity's name. This limited edition Imperial was available only in "Glacier Blue Crystal" paint - Chrysler advertising claimed it matched the color of Sinatra's eyes - and had special "fs" (lowercase) external badging, with a large glovebox placard proclaiming "Frank Sinatra Signature Edition". Inside, 16 cassette tapes of Sinatra titles were presented in a specially made Mark Cross leather case. In the center console of the car there was also a special tray for 8 cassettes. 271 "fs" edition cars were manufactured. The "fs" cost $1,078.
