Separating passenger car body

I've seen some that the side windows need to be pushed in a bit to get the roof off.

In the second photo, you can see that the first full window pictured has a bit of plastic sticking out beyond what the others do.  As you push in those windows (there's one on each side of the car), gently lift the roof away from the car body.  The roof, windows, and silhouettes, if any, are all one large piece.  I have found it helpful to insert craft sticks or popsicle sticks in the gap as you work your way the length of the car.  These are tricky, no doubt, and sometimes the paint creates an extra sticking point.

There is a similar set of windows on the other end of the car.  Repeat as above.

Four of the side windows(2 per side) have raised locking wedges.

The secret to getting these apart is to squeeze the windows in from the bottom or sides instead of trying to reach over the top... hold the car in front of you with the side windows facing to your left & right between your hands.

Press in on the "notched" rear windows with both index fingers using a pushing up motion at the same time to "unlock" the raised tabs from the windows. Switch to the front windows and do the same. Repeat on back windows again... usually by this time you have opened up the roof enough to get a grip on the roof panel and raise it straight up & out of the car.

Don't mar the finish by using wedges or screwdrivers to pry the roof up - it just isn't necessary.

On the chance you do have an early Milwaukee car, turn it upside down and check for 6 white tabs/nubs protruding through the slots in the floor.  If these are present, you must take one more step and remove those nubs with a hobby knife, as they are actually part of the roof casting.  This "feature" was discontinued quickly when it was determined the window nubs/tabs alone were enough(or a service station went to change a bulb on the first one to blow out!).

Thanks to all.  I got them open.

These come apart easy if you have four hands for the four window latches.

I've used a pencil with a soft eraser to help nudge those roofs off -- doesn't slip on the windows and stays clear of the window frames. It's easy for my fingertips to slide on the window portion and pinch on the window frame which tends to make everything stick together tighter. They're kind of like a Chinese finger puzzle that way...
