I guess thats not even the end of the line since there probably are other costs like taxes, insurance and repairs?
I use several types of transportation every day (Bikes, Scooters, Mopeds, Buses, Trains, Cabs) and I pay less then 300 Euro a month for it all. And its much less hassle since I can just start wherever I am and never have to search for a parking space, walk to my car or deal with any maintenance.
