I'm pretty sure it's a background vehicle like most of the others here, unless you count the two that Greg Dulli sits on the edge of(Yellow GM pickup & Chevrolet Camaro).

It is not so badly visible, has it a role?

For what is seen, I am not sure if this one is really worth listing?

So far, the only other picture I'm been able to capture from this round of the 1993 music video for "Debonair" by The Afghan Whigs is this one of the Volkswagen Dasher Station Wagon.

I'll try again to get the Firebird, but I can't make any promises. I'm pretty sure the Econoline and Dodge Diplomat Police Special might be mixed in with the Camaro somehow.
