6 gear manual or automatic

Hello did not think that I have to write the set ….”I’m new here” The new Tucson 2.0 CRDi 4WD Premium 185 hp has come into the near choice of my new business car. Currently I drive a Passat cc 17oPS TDI 6 gear manual gearbox, about 30Tkm/a partly with trailer. I would like to know your experience with the 6 gear manual transmission, positive as well as negative. My motivations why I don’t want an automatic at the moment: 1. Additional costs when buying 2. Additional costs when consuming 3. Max. train load is lower (where the Automatic is currently sufficient) Looking forward to your experience. LG
