Delivery invoice at handover of vehicle

Hello forum, read here for a long time, for a week now I belong to the circle of the C30 drivers (a barent-blue D2) and have a question immediately: My dealer made himself a little unpopular with me when he handed me not only the actual invoice, but also a “delivery invoice” with all kinds of additional points, of which before was never mentioned… Is it usual that also the requirement / issue of the registration certificate part II My dealer wants to have 25 € for this, allegedly this had to be requested by the KBA and was further calculated. Anyway, it was new to me that such a thing is not included in the vehicle price. Also the registration fee for my used vehicle given in payment was put on the bill immediately. And of the refueled 15 liter diesel, which were generously calculated with more than 2.50 per liter, without having commissioned this, I do not talk at all now Has someone similar Experiences made at the vehicle transfer? I have not experienced at other dealers and find it somewhat intransparent. Greeting from the North, Christian
