It's the German movie "Das verrückteste Auto der Welt" known as "Superbug, the Craziest Car in the World" in English.

Hi,

I am new to the site and I've had a film in my head for years and years and after thorough google searches and wikipedia searches, I'm trying my hand at this forum to see if you.

I can only describe the film I'm looking for as featuring a yellow VW Beetle, this Beetle appeared to be full of technological equipment and perhaps in the snow.
I also remember what I can only describe at Citroen 2CV's that were attached at the back of each on for a set of twins. One orange, one green.

That's all that I can remember.

Thanks in advance.
