When GM had it, they screwed it up thoroughly. Their system is/was a hammer, so everything had to be a nail. No room for deviation from the corporate party line. The only thing they did to make it a Saab was put the ignition on the center console.
Of course, that's far from the last stupid thing that GM did in their corporate ignorance.
I checked out a Pontiac 6000 from the Texas A&M motor pool in the late 80's. When I sat down in it and glanced at the dash, it was impossible to read because of the design - all the sunlight coming in the windshield was reflected into the instrument area. Stupid. I then started it and went to adjust the radio - and found that the oversize shift knob on the end of the column shifter was EXACTLY in my line of sight to the radio - I had to lean sideways slightly to see the radio! Stupid, stupid. I then had some reason (I forget what) to pop open the glove box and discovered that the huge latch mechanism blocked the entire left side of the glove box (the side the driver would have to access), and that to get into the glove box I had to practically lie down on the seat and reach around the latch. Stupid, stupid, stupid.
In less than 60 seconds I found three substantial design flaws. No wonder GM got their collective ass kicked for 20+ years. Other than the Corvette, the new Camaro is the first Chevy passenger car that has appealed to me visually since about 1980.
