Hehe autobahns.
In my German days, my usual ride was an old Patrol Jeep with totally max 70 mph, and to add insult to injury, I was usually tossing around with a horse trailer. Sometimes beef cattle on board.
One fine day I got a reasonably new little Golf to play with. I got it to 110 mph, still those bloody Ferrari's kept whooshing by as if I was standing still!
Anyway, Replicant, Munchen is an extremely nice town,I really loved it there.
Be sure not to miss Deutches Museum as mentioned somewhere before, it's really great, and the aviation section is a must-do.
Also, since the Zeppelin stuff is in Friedrichshafen, well if it's the one at Bodensee, that is a most wonderful place. Beautiful landscape.
If you are looking for some old remnants of WW2, try this:

P.S. You get used to the Wessbier after a while, and I wholeheartedly recommend German Rindersalami to go with it.
