Which particular car make and model has been filmed the most in Movies? I say Ford Mustangs my friend says Chevolet

Hi,
I often post/update statistics there:
http://imcdb.opencommunity.be/forum_topic-105-2413-Statistics.html
Currently the top is owner by Ford. Chevrolet is at 2nd place, but with a much lower count. Mustang is at the second place of the models, but the Impala at the 3rd place is close.
Do not forget that these stats are based on what is listed on the site, which only represents a small amount of what can be seen in movies.
Another thing is that for some cars we added a whole list at the beginning of the site, without pictures or more info.
So for example there are lots of Mustang that are listed without picture or role info, but this is not the case for most of the other models.
