23 years old – First own car

Hello together, from next Saturday I am the owner of a BMW 323CI (Coupe). Now the following question arises: Who should I register the vehicle and on whom the insurance?! Possibility 1: register the vehicle on me + partial casket with SF 1/2 HUK Classic fare (880EUR/year) Possibility 2: register the vehicle on me + insurance on my father as first car with SF20 fully comprehensive HUK Classic fare (545EUR/year) Possibility 3: register the vehicle on my father + insurance also on mei HUK Classic fare (475EUR/year) Which of the three variants would you recommend?! With variant 1 I would come to SF1 on January 1, 2010, but unfortunately I only have partial cascades. However, I assure the ride on my father (part cascades to total only 50€ difference) and pay almost half less, but unfortunately no SF classes gradation. What do you think of the HUK24 (Classic fare)?! Thanks already for your answers! Greeting Rene
