Another Mercedes Rental

This time around I am renting with Hertz - they had the most reasonable priced automatic gear rental. I got again a Mercedes A-Class, this time a A180 CDI. It is a diesel fueled car, and you can tell right away from the rather noisy engine. During the drive on the Autobahn it is not that annoying. Other than that, the car seems fine. I can't see a difference to the A150, other than the engine.
