I've worked on a lot of Autocords. All in all they are very sturdy cameras. Other than the focus helical grease, and many of the shutters being prone to gumming up with old oil, they don't need much in service.
As to the rollers, take a cotton swab and rub them side to side. this will often show you the snags. It'd be worth rubbing them down with lighter fluid or alcohol. Also make certain that they actually roll, including the one on the bottom of the back. A small drop of oil on the ends never hurts (small!!! yes, oil on film is not good).
The shutters are basic leaf shutter designs. Any repair person who can work on a standard #00 leaf shutter from the 50-60s will be right at home.
With proper recording of positions of the focus helical parts, they come apart and go back together easily. The four set screws that hold the focus lever to the helical are staggered eccentrically, and there are divot marks in the helical for reinstallation. Mark the inner helical part for top center location at infinity and all will go smoothly.
The wind system is basic, and any repair person who has worked on a Rolleicord or YashicaMat will be fine.
Probably the worst thing about working on some Autocords is that the old skin turns to cement on some and it very annoying to remove it. And it must be removed to do some of the work.
Well, my point in rambling on is to make clear that the Autocord is not beyond the ability of an experienced repair person, even if they have not worked on directly. I know that not many made their way to Europe, but they are not bizarre one-off mechanisms.
Oh, most likely you will need a new mirror.
