I've joined
stattauto and I have to say I'm really impressed so far.
I know its been more fully covered elsewhere but basically you pay 7 Euros a month and you can rent one of their cars for whatever you want. You pay an hourly fee (€1.70 an hour for the smallest car) and an amount per km (17cents/km for the smallest
including petrol). They have 450 odd cars (including estates/wagons, cabrios, minibusses and vans) in 60 stations around Munich. There are 3 stations each with at least 4 cars within 5 mins walk from me in
Schwabing. You just book online (or call) and then swipe your card on front of the keysafe at the park place and it opens and gives you the car key.
I have managed to book a car online for right away, walk round, drive it to a shop and return it all within 30 mins with a cost of €4 or something.
Pretty damn good.
