The shown features echo what (in addition to the core Saab characteristics) had been needed to make that car a real competitor for not only the Teutonic Three. Design-wise the sedan drawings seem to be closer to the final thing than those of the combi, which is kind of close to the 9-x concept. The more you look at it the more you get all the quotes from the several concepts that Saab had shown at that time.
While I also liked what I saw of the Castriota 9-3 I have to admit that Simon was on a good track to develop the Saab design language one step further. Especially that top left drawing on the Sedan image is something I had surely bought.
As with many things, it’s too bad those never saw the light.
