Important question regarding beginners

First a hello in the round… I have the following “problem”. I have to buy a Opel Omega 2.5TD before spring. With the HUK24 calculator it came out that I have to pay about 1370€. The insurance runs on my father, but my percentages (140) are “considered”. DH he is very expensive. (Every car for beginners I think, an Omega is not the typical race car for teenagers) But now something else: A colleague drives a porsche 924 for 350€ in the That’s why the question is: can it be arranged in such a way that the % of my father is taken into account and not my 140? Imagine this so that my dad is registered as the main driver and I only drive “on and off” times. You insurance experts can certainly help me there?! 1370€ is just a great amount! If you know how to make it cheaper. I would thank you for that. bar! Of course on a liability basis MFG WAR
