Decision-making aid Clio/Twingo/Seat Arosa/VW Polo

Good evening, I now have my driver’s license since February and now I have to get my own car, since I start my training in October and have to commute there within a radius of about 50km. My requirements for the car would be: -reliability -safety -price up to a maximum of 3000€ -on the motorway the car should also be able to drive reasonably pleasantly (and fear-free). -Dental belts and WaPu should have changed for the second time if possible and the car should be so In my price segment only the Clio, Twingo, Polo and Arosa were built after 2000/2001 (where the facelift was at least with the Renaults). Which car would you advise me on and what should be paid special attention to when buying? (So where are known weak points like for example with the Twingo the brakes) To which motorization would you advise me at 50-100km highway every day? and last:Which car is in the insurance a m Cheapest? Greetings, Marco
