I wrote to www.barchettaclub.fr informing about that mistake and.....all is a joke. This is their answer: "Hello. Don't worry, it is only a joke organised by a friend, because my white barchetta was build from a barchetta who falls into the water in 2003 :-)))
In France every barchetta owner knows my white barchetta and everybody knows that it is a joke, we made a big comunication job on this rebuilding."
Tha's all folks. Anyhow I must be more careful with the images I can find in the web.

You were right. Certainly is a fake, a big fake.
That's the correct picture


And, obviously this french page is wrong

[n/a]?

how do you want to find in a 1977 movie a Fiat Barchetta, a model which was started in 1995 ?

Like you, now I don't remember that scene, but look this Fiat Barchetta french page

Well as I have this movie I'll look for it.

I think is a fake... I saw this movie, and this scene don't exist.

In Spain: "La espia que me amó"

One more car that I have found. It's a mixed Fiat Barchetta submarine-car, and only used in this scene. 2 stars
