Yeah I just took guesses on some of them, the Imperial, Olds Delta 88 Satellite etc, I'm pretty sure of the year though. I thought those Impala's might have been Caprices but again I wasn't 100% sure.

I think they are just guesses, the LTD also being one, as that style went from 1982-86, no way to tell 1985 specifically.
The Impalas are both 1981-85 models
The Pontiac is actually a Bonneville from 1977-79
The Tempo is an 1984-86
The Mercury Gr Marq is a 1983-85
And the Olds Cutlass is a 1982-1986

Just a question: How can you tell the specific years on some of those cars, especially the Impalas and the Grand Marquis?

The right ratio is probably the usual 2.35, but the different is not very big anyway

Nice pics, but two of those "Caprices" are actually Impalas. I believe that Kenworth might be a T-600.

Took a few pics from the movie Alien Nation I have on DVD, after I got rid of the black borders I ended up with a funky 2.20(!) aspect ratio....but the pics don't seem to be distorted other than being very wide. Most of the driving scenes are at night so most are dark but I snapped a few cars of interest I think.
