I guess my answer is no one knows the history or has any documentation about it.

plus the two ads I show above from 1929 clearly indicate below the pictures what they are, under each Oakland and Pontiac it states The Cabriolet Body by Fisher so even though you state no literature you have indicate a Cabriolet model, why would the ads call them that?? it just adds to the mystery eh?

Firstly try not to read too much into it or assume, I missed a break, so what I meant to type was Pontiac/Oakland Cabriolet, as the brands were related, Oakland came first and GM brought in the Pontiac name to fill price gaps, in 26, and to their surprise the Pontiac priced above Chevrolet but below Oakland a tad but with Oakland features sold quite well, in fact by 29, GM sold 163,000 more Pontiacs than Oaklands. By 31 GM decided to drop Oakland and keep Pontiac. In the 20's all the GM divisions were starting companion make programs to fill price gaps between models, so it went Chevrolet (cheapest) then Oakland but a huge gap was there, the Pontiac was priced in that gap, Oldsmobile got the Viking, Buick got the Marquette and Cadillac got the LaSalle, none of the companion cars survived the depression BUT Pontiac not only did it took over the Oakland slot and Oakland was dropped. My question was directed soley at the Cabriolet history because what is written makes no sense to what I see in ads or being sold, one site claimed the Cabriolet was a one year 29 model and was dropped half way through 29 due to the depression, I see ads for Oakland and Pontiac Cabriolets that are before and after that year. I have not not been able to find anything definitive about the Cabriolet model, it's build numbers, it's span of years, etc.

I would like to ask if anyone knows the correct history of the Pontiac Oakland Cabriolet. Some of what I have read seems to be wrong. I read that the Oakland cabriolet debuts in 1928, then Pontiac has a model in 29 the same year they both get the big 6, then the crash and cabriolets are dropped in 29, later Oakland is dropped and Pontiac survives. Then I see cabriolets for sale that are 30’s, very confusing and does anyone know the number of cabriolets built? Thanks

This doesn’t make much sense, if the valves aren’t working the engine would still have compression on some cylinders, some pairs may have one open but some would be closed, you’d have to pull the valve covers and turn the engine over and see that none are moving then pull the intake and see the cam is/isn’t moving, sounds like the piston rings are gone,

I am confused about the cabriolet, I read that it started as a 1928 Oakland model and then Pontiac made one but only in 1929. I know that due to sales GM shut down Oakland and kept Pontiac but what is the true history of the cabriolet model?
