Car with low insurance rating

Moin, I have the problem of buying a car, it’s not really about the car, it’s just about reliability, consumption and the most expensive, the insurance.(become 18) I’ve already noticed that a car in the initial phase loosely consumes 250€ in fixed costs. Only I need a car for say 2000€ +- 500€. This should already offer maximum comfort, consumption of max. 7-8l and also 4 years. Annual output I plan 15000km, it can also be 20000km. It will be 20000km. 50km at a time mainly, but also individual journeys of 250km are done every now and then. Since my father is something special he only believes in small cars and they would be anti-capitalist… Well, it should hold and offer some comfort. The car can be German or Italian. Alternatively, one can imagine a leasing, will probably be at the 300€ monthly cost – is probably more than 1000€ of the fixed cost of your own car. he only makes up for a low fuel consumption. With my bill this is the case with about 7l petrol at 1.50€ and diesel for 1.40€. Do you have similar experiences? Greetings Jens
