Well, I do not like to take images from websites without explicit permission.
But you could for example ask to the site (and then I put a link to the site on the movie page).

It is a Golf 1 indeed...I found some images on a website also, but I think the policy was not to use images from other websites, wasn't it?

Thanks

For the Golf, I guess it is a Golf 1 ? (though could be a Golf 2 as it was already sold in 1985)
