I stongly disagree to this. I think uncommon cars should be preffered, even if they are more background than others.

To give my opinion one the subject, I think we should have some rules. But I think the admins should be wise enough to apply those for themselves. Of course it cannot hurt to tell eachother if we think the rules are not met.

I think in General we should stick to these rules:
They could be listed as background cars, even with a lower quality image if:
1. The make or model is uncommon
2. The make or model is not uncommon but it is a Special Version agg. limited edition of a model (and can be identified likewise)
3. The car is set in an ackward location/country where it is more uncommon, or where one would not except this kind of car.
4. The car is delibaretly planted on a movie set (and possibly could be in a wrong time area or place area as a result of bad casting)

All other background cars should be quality images, with at least 75% of the car visible, not too far away, but no need for only 100% full frontal shots aswell as long as they would be easy recognizable. Otherwise they should not be listed at all.

In my opinion pictures of car parks could very well be included as I love those very much. Furthermore I do not think it is wise to go deleting images some else has uploaded. I am against that.

And also, but then I speak for myself, I love Citroën GS's and GSA's, I do not care how tiny the image is, I collect all images of them I can find, and not only from movies, but also from old magazines etc...
