Low-insurance car

Hi someone knows if there’s a list somewhere, which car has about what liability class? I’ve been annoyed with tariff calculators of insurances because they’re all so confusing. reason is: I’m going to be 18 next month and looking for a car that’s very cheap in maintenance (sprit consumption, insurance) and wanted to find out what the different models cost about a year. I can let the car on my father and the insurance from my 125er, which runs on about 30%, take over. since there seems to be no cross-brand forum here, I also write the rest here: the car should cost less than 1000€ and be very cheap in maintenance. on any comfort I do not put much value. in case of minor problems or reperatures I think that I have the possibility to fix this myself. I have calculated the prices already for several cars (ford fiesta, opel corsa, opera astra, vw polo ….) but there have always come out very funny results with the tariff computers. what do you think still for cars in question? I don’t mind if the car has a little more ps for its size and maybe is optically and technically a little more sporty. it doesn’t necessarily have to be a small car, but I think that the cheaper ones are. I’m sorry that I’m asking for several things at once, but I didn’t know where else to write in the rest.
