Sorry if this is the wrong area to post an amateur question. My car is a 70 GS clone, but it’s a post car (frame around front windows), I was told there was never a GS post car. I’ve been trying to find info on why some skylarks were post cars, and some were not. I like mine being a post, but I’m just curious. It’s strange to me that GM would have an option like that, I would think that production cost would be higher
For the '70s, the post car is billed as a 2 dr sedan in the brochure (link below) It was usually cheaper than a pillarless hardtop. And a post car is more rigid body wise. The pillarless hardtop rose to popularity in the 1950s, and were often the glamor cars of the range- as well as the convertibles. It's not my field, but the post cars were generally cheaper price wise. As for the production cost, it's not so clear cut. A car without the extra strength of the center post will need reinforcement elsewhere in it's structure. And frameless windows are harder to make and seal than a framed door window. That's my take, the experts will know better than I. Personally, I'm a sucker for hardtops. I love the lack of the center post, even though it has it's disadvantages. http://www.oldcarbrochures.org/Unit...l Line/slides/1970 Buick Full Line-50-51.html
Actually there were GS sedans (post cars) built from '65-'69. I do not have an answer to your original question however. I personally like the post cars very much and have a couple of them myself.
Cool thanks for the info! I definitely like the look of a hardtop style, especially when all the windows are down, but also like the look of mine, I didnt know there was difference until I bought mine and people pointed out that it was a post
