Rented cars for business and personal use from Kassel Nord, never had a bad experience. First rental I got was an upgrade from CDAR to a BMW m135I which was a great suprise. Once I got the keys to an A3 which would not start, but the team quickly found a good solution in an upgrade to an A4 estate. 5 stars as I've only had good customer service and it's the only branch where I've never been given the dreaded Opel Insigne.
