I was in the city this afternoon and saw the set of the movie-and most importantly CARS!
The filming was on and around the steps of Parlimet http://wikimapia.org/#lat=-37.8110872&lon=144.973239&z=19&l=0&m=a&v=2
(look for a link that says Knowing on it)
There was a:
Newish Ford F-100 series, in dark blue, and was dirty
New Pontiac Trans Am, Purple
Audi A4, silver
I believe these cars were LHD, but I am unsure, as I did not get a long view at them. All these cars had Massachusetts plates, which were real plates, but am unsure if they were the cars original plates.
I just thought I should let you know about this find.

also a Humvee in filming, and a Jeep

2002 is more than 5 years old

So? I was comapreing to a Bandit Trans Am, so this is a newer model

Sure, but it could be understood as "brand new" (hence Taxiguy's comment)

True. Can these cars please be added?

They will, but not as pictures or even known vehicle roles. It is wise to request cars and movies to be updated to the site in the contributions.
