Hello there. What vehicles do you want to know about exactly? Are you also looking for information on the literally hundreds of vehicles that were present throughout the shootout or just the major vehicles?

Obviously the main ones that come to mind are the Chevrolet Celebrity, the (Dodge?) truck at the end, and the various LAPD cruisers.

This page has soom stock captures from the shootout, mostly of law enforcement vehicles that were at the scene:

If you can be more specific on this then it would help.
