Car Rental in Munich

I'll be in Germany towards the end of May for 6 days and will be picking up a car for the period. Had a look a the BMW on demand but the site is crap and don't seem to offer that far in advance. And it doesn't seem to be particularly economical bearing in mind it's the manufacturer hiring out the cars.

I'm not planning on going overboard anyways so anyone have any experience of car renters in Munich and any ones in particular to stay away from?

Rich :-)

I have always found SIXT very good, quick search there for Munich and they have a large range of cars from VW Polos to M3/M5 to Maserati's...

+1 with Sixt. But book a car EARLY!
