Thanks for sharing that Saab video. I think the first year of 4 stroke engines was '67? Free-wheeling- yep, mine had it. I also had that same sticker on it! Made in Trollhatten by Trolls. My grand-dad bought the car in Sweden in '69 and they toured around and then shipped it to the states. Awesome car. Wish I still had it. Solid as a tank.
