I found a 1960 Opel Kapitän in From Russia With Love. It is painted like a turkish Taxi and it appears in the background when Bond arrives in Istanbul.

I've got the DVD, so I'll find it and add myself (unless it's too background). But thanks for telling us!

Found it, thing is it's more or less the same image as this: http://www.imcdb.org/vehicle_18802-Rolls-Royce-Silver-Wraith-LELW21.html

So I'm not sure if it's worth making another listing. I'll see what others think (although some people are happy to list any old background car).

You could find another shot for the Rolls, and then use that one for the Opel.

For the Opel we could use the pic that is now for the Rolls-Royce Silver Wraith Limousine Park Ward [LELW21] http://www.imcdb.org/vehicle_18802-Rolls-Royce-Silver-Wraith-LELW21.html
And change the Rolls pic using the posted here in first answer

Done

BTW, your nick name in the site is also 'robikumpel' or is it different?
