Better pictures for the cars already listed were asked for, and here are some I took today. 
Dodge taxi cab used by Denham at the beginning.
Ford taxi that takes Ann and Denham to the docks.
Ford taxi that Jack gets chased by Kong in.
The investors' Chevrolet.
The as-of-the-moment unknown background car.
And now for some not already listed.
Army car with a machine gun mounted in the back. 3 stars.
Army truck with what appears to an artillery cannon (?). 2 stars.
Army truck. 2 stars.
Army truck. This one's a troop carrier. 2 stars.
Police motorcycle (on the left). 2 stars.
Truck. 1 star.
There's tons of background cars, but I didn't feel like uploading all of them so they'll have to wait.
