That "Breezeway" design has been around since about 1953-54. Mercury had a concept car called the D-528 or Beldone.
@pete-rovero I like them both, Pete and John, even though I'm not familiar with either. I think I'll try a little research.
(later) Okay! I've found some good information. Here are the sources for those who have any interest in two dream cars of the early and mid-1950s. One of them, the Plymouth, has been modeled in 1/43 scale by Matrix and sometimes shows up on the used markets. I don't have it. The Mercury was featured in a movie, "The Patsy," and that's where the "Beldone" name originated.

Mercury D-528 / Beldone

And here's a little more:
The 1955 Mercury D-528 (the 528th design concept to come out of the FoMoCo Engineering Department, it was not a "show car" but an engineering test bed) which is identified on your website as having had a minor role in an "Outer Limits" episode (TV series) had much greater exposure as the "Beldone" in the 1964 Jerry Lewis movie "The Patsy". The car had been modified by George Barris for remote control operation of the doors, hood, and trunk; he also changed the nameplate from "D-528" to "Beldone" at the request of Paramont Pictures. However, the car looked essentially the same, despite a new paint job. The car stayed with Paramont for quite a while, showing up in various TV shows and movies, until it returned to George Barris and eventually passed into private hands.
The Mercury 4-doors are definitely on my must-have list.

Thanks, David, for your research on these two "survivor" dream cars. I was fortunate to see both of these cars at the Petersen Auto Museum years ago. The Plainsman was not restored and was a bit rough as in the pictures that I posted of it.
Joseph Bortz had his collection of dream cars featured at the Petersen in '97-'98 which I was fortunate to see. I have the event poster hanging in my house. I can't believe that was 25 years ago!
@pete-rovero Many thanks for your comments, Pete. I have never seen such 1:1 cars, only in our much smaller versions. I remember as a boy admiring the new Kaiser Darrin and Chevrolet Corvette, but that was only on the showroom floors of the dealers. I still remember them vividly. (Click on picture for enlarging.)
(later) And I just looked up Joseph Bortz. Thanks again!
