They definitely are manual windows and seat. And for that matter manual door locks. It boggles my mind that is what Buick did, but it is in fact how they did it. http://www.stage1registry.com/registry/Zone_Office_Stage_1_converts.pdf
Chris is correct both the Zone car I had and one I have are manual windows and seat. I wish Buick would have loaded them up but they cheapened out in 72. I do not care for the 71 body color but like how it is optioned. I was actually going to add all the options to the one but decided not to.
The options pictured all look correct to me. All 25 (1972) Zone Office cars were built with the exact same list of options: Stage 1 performance option, turbo hydra‐matic 400 transmission, power disc brakes, power steering‐fast variable ratio, sonomatic radio (AM), stereo tape player, rear speaker, through bumper exhaust extensions, super wide oval group (G60‐15 tires with 15x7 chrome road wheels), air conditioner, color coordinated custom front & rear seat belts, soft‐ray tinted windshield, front and rear bumper guards, bumper strips front & rear, outside rear view sport mirrors, tilt steering column, convenience group (lighting), instrument gauges with rallye clock, and a rallye steering wheel.
Update.... I have spent about 5 hours over the past two Sundays looking over this car. I have verified the majority of the numbers on this car. In addition to the afore mentioned time I have also researched as much as I can in my personal library an asked several of the 72 zone care experts to validate that this is indeed a zone car AND that I believe it is the Denver Zone car. As such, it have lived it's entire life to this point in Colorado in either the Denver or Colorado Springs area.
Nice looking project but it is going to be an expensive venture. My first Zone car went out of control and the second Zone car even got out of hand with beautiful original sheetmetal. Even finished seems they do not get a lot of love. I really like the colors but prefer more options. Below is my current one. .
