New car more PS-wise or stupid?

Good Tach, I would need advice from experienced people who were in a similar situation to me at the moment. Of course I am also happy about advice from other people. I might have to get a new car. I was thinking of a Ford Fiesta ST from 2013 o. 2014. I finished my apprenticeship as an administrative clerk in the public service last year. After my training I stopped working because I was travelling around the world. On the trip my savings went on from the training. Now I work again. Have an unlimited contract, full-time job, live at home and have no additional costs. At the moment I drive my old Focus year 99 (first car). However, it gives the workshop soon the spoon off. More and more repairs occur. At the moment a few things are broken. I got a quote from the workshop. Over 1000€. That’s how much the car is I would like to finance the Fiesta. I still have the money and could afford it. The fun of driving makes me really interested in buying it. I’ve been driving the ST before. Well and in 3 years, who knows, I might not live at home anymore and then I wouldn’t have any money for such a car. So I wanted to take the chance now. Now I’m still young and have the money. Only this financing makes me stubborn. I’m not so the fan of it. How was it with E Have you financed a car yet? Have you regretted it? How would you behave if you were in my place? I am looking forward to your answers LG Flo
