Mike, was your MoFo in the same "tiptop" condition as the specimen we are talking about?
Mine's a 72 with hundreds of thousands of miles on it and I keep it maintained as a daily driver. I am fully aware of minor problems I have so I fueled it up and left for Laredo. I had changed my carbs to some Chinese 38's two days before so I wondered about how they would perform. I threw a full size 235/45/17/spare tire in the trunk just in case, and in Texas it came into play.
I read this guys "trouble" list and there's nothing on there that would really concern me.
If the fuel pump is wired oddly - fix it. Connect the wire to something that will work.
If the carburetor linkage is flimsy - take it easy on it.
If the fuel gauge is flaky - use your phone and map apps to see how far you've traveled. Any time you stop, fill it up.
The temp gauge is not accurate - it should be relatively accurate. Given that this community largely reports engine temperature as a time of day, 4 o'clock is hotter than 3.
Heater doesn't work? Layer up. Wear warm socks.
Wipers? If they go up and down, there's new blades available.
Only one key works? How many do you need?
Other than that, we’re told the Bavaria is solid: smooth, tough and German, with a fine ride, good brakes, healthy tires, new CV boots, no leaks and, weirdly, seats transplanted from some newer Acura.
Sounds like mine, except I have Subaru seats and some other odd parts.
