Hi,
Initially I was trying to identify an american car used in the french movie: On a volé la cuisse de Jupiter, 1980. Browsing along, I fall on your phenomenal data base where I did not find any hint unfortunately. So I suggest to add the following two movies to your data base, they contain a wealth of french cars from the seventies.
"Tendre Poulet", Philippe De Broca, 1978
"On a volé la cuisse de Jupiter", Philippe De Broca, 1980

And if someone could kindly identify the american car chasing the Greek train in the second movie, It would be great.

Thanks a lot
Mayninth
