These are more screencaps that I added in the comments section of other vehicles. The first 2 screencaps can be found on the 1974 Pontiac Firebird page:

The 2nd screencap looks like the same one submitted in a previous post for the Cadillac or Datsun:

The 5th screencap looks like the same one submitted in a previous post for the Mustang (I think vilero said it was too background):

As I mentioned in my reply to the images submitted yesterday, now in the old contributions section, this is one of the things I was concerned about when I started doing the show. There are so many cars in this show, especially from parking lot and street scenes. Instead, I have added many as thumbnails in another vehicle's (the most prominent in the frame or the primary action vehicle) page rather than add a page for them. I don't think it's necessary to create new pages for all these background vehicles instead of just commenting on them in the page where they appear as thumbnails.

As I also mentioned in my reply to the images submitted yesterday, I've been pretty picky when it comes to adding background cars, but I still often add 10 to 12 vehicles in an episode. Over 119 episodes, this show could end up with well over 1,200 vehicles.
