What is that old movie in the 70s or 80s has this guy who like an agent he high tech gadget yellow car could be a Volkswagen and at least part of takes place Lisbon?

The movie you are thinking of is "The Man from U.N.C.L.E.", a 1964 American comedy spy film directed by Guy Ritchie. The film stars Henry Cavill as Napoleon Solo and Armie Hammer as Illya Kuryakin, two agents from the United Network Command for Law and Enforcement (U.N.C.L.E.) who are forced to work together to stop a criminal organization called THRUSH.

The film is set during the height of the Cold War and features many of the tropes of the spy genre, including high-tech gadgets, fast cars, and beautiful women. The yellow car that you mentioned is a 1964 Lincoln Continental, which is used by Solo and Kuryakin throughout the film.

The film was a critical and commercial success and was followed by a television series of the same name that ran from 1964 to 1968.
