This is really interesting, I don't believe I've ever seen one like it before. Were many made, or was this a prototype?
My parents never owned a S/W (nor an S&W, now that I think of it!). But then, there was only my folks, and my older brother and I, so no real *need* for one.
But, my brother and I did both end up owning one, mainly because, at that time (early-to-mid 80's), we were buying whatever vehicle we could afford. I had a 1974 Chrysler Town & Country Wagon, non-woody, two-tone blue, with a 400 c.i., and fender skirts. You wanna talk about boats...this thing was a battleship! I once hauled 10 people to a concert in it, (and my passengers said I drove it like a sports car), and on two occasions I hauled a full-size motorcycle in it. It looked pretty dang sharp when I first got it. But...it quickly turned into the biggest pile of garbage I ever owned.
Electrically, almost everything in it failed or broke. Every power window broke...always while in the *open* position, and usually during the winter. The tailgate power window was the worst, as you had to use it every time you wanted to open it downward, as a true "tailgate", and not as a door. It rusted to bits, particularly the aft section. Both rear wheelwells completely rusted out, so that I had to keep my spare tire on the rear deck, because the normal storage area for the spare was just behind the wheelwell. That car left me stranded more times than all of my other vehicles, combined!
At about the same time, my brother had a 1970-something ('73 or '74, I think) GM wagon...I believe it was a Chevy. His experience was similar. Not so many electrical problems, and I actually don't recall it leaving him stranded...but plenty of power window issues (and it had the "disappearing" tailgate, which I believe would get stuck in the down position occasionally), and it was a rust-bucket as well.
I'm currently driving a 2001 Dodge Grand Caravan, which I inherited from my Mother. I only continue to use it because its resale value is negligible, and it only has 50,000 miles on it...so it's inexpensive transportation. While I'm no fan of mini-vans...I'll take one of them over most of the older station wagons, any day of the week! They're more comfortable, more fuel efficient, and they can haul more cargo, than most wagons. Granted, they aren't as "stylish", but I usually choose my vehicles more on considerations of utility than appearance.
