I did ED.....
You can easily get a car $1K over its ED price if you do your hmwk. (overall savings are over $6K compared to MSRP price) I used miles for everything else so the savings were pretty big.
I've only spent 5 days in Munich and did drop off the car the same day i picked it up. i've been to Munich many times before so the whole tourist / visiting Europe thing was not a concern for me
PM if you have any questions.
