Beginners, Leasing, Buying

Hey friends of the night, since I haven’t found a suitable post about my problem in the Sufu I thought I would describe my problem and hope for help. So I’m a beginner 18years old, for 8 months the driver’s license and drive daily 50KM. Currently we only own one car and this is always complicated because my father is also working. The insurance (Allianz) offers me the following. I can insure myself with SF 1/2 75% since my father just there versi This is the problem: he works at Benz and can make a factory member leasing where I can make an A 180 list price 36,990Euro for 292,85Euro for 12months at 8000km, insurance and service Incl.. Now the question is more worth a leasing with a novice or a car purchase up to 8000Euro, whereby the insurance comprehensive etc also costs 110-200euro mtl with the vehicles I want.
