I ask for purchase advice

Hello I am looking for a car for me and am very unwise because I am confused by my acquaintance circle “something”: “just no Opel or Ford”, ” never buy you an Italian “… I think that you may have more experience and can help me better. First of all to my person. I am female 21 and am still in training. I drive about 200-250km a week. It is very important to me that my car is reliable (I am three years with a polo bj. 2 I can’t spend more than 6000 euros. I would like to have a car from bj 2008/2009 and up to 80t km. A bit of ps wouldn’t hurt me either 🙂 from approx. 100ps. I like the fiat 500 really good only I get here and there with it that it is not reliable and that it is no longer usable from 100t km because constantly something is broken (?!) Maybe you can tell me something about it. I also have Testberi read on the Internet and they are mostly not of the same opinion. Do you have any other suggestions? I would be very grateful about helpful answers.
