Car (compact, coupe, limousine if needed) searched for 500€

Hello together, so slowly but surely I want to separate myself from my Peugeot 206 (88PS) to try out something new I’ve been thinking a lot, but I think – I think – just too much back and forth. I have so many models in my mind, I just don’t know what’s right and what’s wrong. In any case I want a car that is a little more stable and safer on the AB. The Peugeot is quite sensitive as a small car at speed 120km/h. As written above, a mixture of power and economy would be ideal, but whether 8 or 9 liters, should not be decisive now, if the 9 liters bring much more power with them. In order not to steer it too much in one direction, I let my favourites out here first. Thanks in advance.
